POTTS 
WAREHOUSE SERVICE 

Potts Warehouse Service is now in its 
123rd year. It has endured because its 
patrons, some through two, three, and 
even four generations, have found it de- 
pendable — dependable because an un- 
selfish devotion to the best interests of 
the customer has ever been held as the 
main objective. Our service today is but 
little changed from our beginnings, i.e., 
a PERSONAL CARE for every order 
or inquiry, no matter how large or how 
small. Our men are trained to high 
standards, both personal and technical. 
Because our business is necessarily 
divided into departments, we can best 
serve you over the telephone if you will 
ask for one of our men who specialize in 
the particular steel or commodity you 
desire. We can also serve you best, if, 
when our outside men call upon you, you 
will give them the opportunity to discuss 
your problems. They are trained to an 
accurate determination of your needs and 
they will keep your interest first.

THE STEEL WAREHOUSE 
OF TOQAY 

The modern Steel Warehouse is not merely a place 
where large quantities of steel and steel products are 
stored, nor is its only function the ability to make quick 
deliveries. The successful warehouse of today must have 
a highly trained staff, with both sales initiative and com- 
plete engineering and technical knowledge — men eager to 
serve and with a keen regard for the customer's interest 
as their primary inspiration. To counsel and assist in the 
selection of the right material for each purpose calls for 
an intimate knowledge of the chemical, mechanical and 
functional problems involved. It has been our aim and 
constant endeavor to perfect such an organization. 

Such a warehouse must also have as complete a stock 
as is possible of the almost limitless range of grades, kinds 
and qualities that have been developed to meet the varied 
demands of modern industry. All the materials herein 
listed are of the highest quality and workmanship that 
we have been able to obtain. Our service facilities enum- 
erated are likewise the most complete and up-to-date. 

We believe the comprehensive information gathered 
here will prove of much benefit to the regular as well as 
occasional buyer of steel and other metals. 

We would record our keen appreciation of the patronage 
extended to us in the past, and express the hope that we 
may merit the opportunity for further service.

WAREHOUSE CUSTOMS 

Sales: 

Sales are made subject to strikes, accidents 
or other unavoidable delays. 

Cancellations: 

Orders are not subject to cancellation except 
by our consent. 

Deliveries: 

Materials from Warehouse are usually shipped 
same day order is received. On special ma- 
terial, or where some preparation must be 
made in our warehouse, deliveries are sub- 
ject to possible delays, but extra care and 
attention are given to these orders. Orders 
for mill shipment are based upon mill 
schedules. The intimate knowledge we have 
at all times of mill conditions enables us to 
often give the earliest delivery possible. 
Sufficient allowance should be made, however, 
for unavoidable delays. 

Telephone Orders: 

We have a specially trained force to receive 
telephone orders. The utmost care should be 
used in transmitting these and repetition 
made to avoid error. 

Confirming Orders: 

If not so marked, we are not responsible for 
any expense by reason of duplication. 

Boxing: 

We box and charge at cost all shipments 
which in our judgment require this protection 
during transportation. This would include 
small lots that cannot be properly handled 
otherwise. 



WAREHOUSE CUSTOMS 

Defective Materials: 

We will replace any material proving defec- 
tive, but under no circumstances will we allow 
or be responsible for damages or labor or 
other costs. 

Returns: 

No returns will be accepted unless definite 
arrangements have been made with us be- 
fore materials are sent back. All such ma- 
terials must be in good condition and labor 
and other costs will be charged where we are 
not at fault. When complaint is made, full 
opportunity must be given our Engineering 
and Metallurgical Department to ascertain 
if materials in question are being properly 
handled. 

Cash Orders: 

Cash or C. O. D. orders for special or cut 
materials will not be accepted without a cash 
deposit. 

Extras: 

All extras given are in cents per lb. 
Intermediate sizes take next higher extra. 

Responsibility for Damaged Goods: 

Our responsibility ceases upon obtaining a re - 
ceipt from transportation company, showing 
materials in good order when received. 

Quotations: 

All quotations are subject to change without 
notice. §

Analysis 

.35/.4S Carbon Open Hearth S. A. E. 1040 Steel. 

Quality 

Precision Finish ELASTUF MEDIA, to insure freedom 
from mechanical defects, is manufactured from specially 
selected billets, and is also made under grain size con- 
trol, which results in excellent uniformity and improved 
machinability. This grade is carried in stock for pur- 
poses requiring greater strength and accuracy than 
ordinary cold finished steel. 

Sizes 

W to \y % * Rds., Inch— Produced by Grinding and 
Polishing Cold Drawn Bars. 

l^g" to 4" Rds., Inch— Produced by Turning, Grind- 
ing and Polishing Hot Rolled Bars. 

Accuracy and Finish 

Guaranteed as follows: 

Up to 2 ■& " Inch 2 V 2 " and Larger. 

Plus .000, Minus .002 " Plus .000, Minus .003' 

The finish is bright and mirror-like, and bars are straight 
and true round. 



Physical Properties 



Tests taken from lH* to 2" Round:

Machinability 

Because of the high carbon and the excellent balance of 
its other constituents, Precision Finish ELASTUF 
MEDIA machines readily, there being a complete 
absence of tear and drag. Sizes 1-&" and larger do not 
have the tendency to warp as do the Cold Drawn 
steels.

Boxing and Handling: — The utmost care is necessary 
in handling these steels, if the high surface finish is to be 
maintained. We use leather and burlap-covered racks, 
crane chains and trestles. On deliveries by our truck, 
material is handled in boxes, which we take back, and 
for which we make no charge. Freight shipments must 
be boxed. We assume no responsibility for arrival in 
good condition unless properly boxed. Boxing is charged 
for at cost.

COLD FINISHED 

ELASTUF PENN 

MACHINERY STEEL 

We list some of the many advantages offered 
by the use of this finish: 

1. It will fit collets in your automatics, and 
machine beautifully, being manufactured 
under Grain Size Control. 

2. It possesses a desirable combination of physi- 
cal properties, the tensile strength and yield 
point being considerably higher than Hot 
Rolled ELASTUF PENN: Pages 125 129. 
This improvement is especially noticeable 
with the yield point. 

3. It can be used instead of un-heat-treated or 
annealed Cold Finished Alloy Steels as its 
physicals are equal to and in many cases 
superior to such steels, its machining qualities 
much better, and its cost appreciably lower. 

4. It does away with the necessity of carrying a 
stock of several grades of steel as it is a fine 
"general purpose" steel, combining the ad- 
vantages of cold finish size accuracy, excel- 
lent physical properties and good machining 
and heat treating qualities. 

5. We recommend its use where such Cold Fin- 
ished steels have been used as 

S. A. E. 1020-1120-1112 
1035-1040-1045 
3130-3135-3140} 
2330-2335-2340 Annealed 



Consult page 127 for list of applications where 
Hot Rolled ELASTUF PENN, pages 125-129, 
is used, and in general the same list may be 
taken as a guide. It should be noted that in 
common with all cold drawn steels, Cold Fin- 
ished ELASTUF PENN has considerable in- 
creased strength figures over the hot rolled, but 
some reduction in ductility.

POTTS JJ— SOFT STEEL 

GUARANTEED DOMESTIC OPEN HEARTH 

Quality: 
Guaranteed Analysis. 
Manufactured under Grain Size Control. 
Rolled from Specially Selected Billets. 
Free from Mechanical Defects. 

For jobs requiring — ■ 

Forging — Welding — Machining 
Hot or Cold Bending 
Carburizing — Heat Treating 

Analysis: 

Uniform and definite analysis for all sizes: 

Carbon 15/.25 

Manganese 30/.60 

Phosphorus 045 Max. 

Sulphur 05 Max. 

(Conforms to S. A. E. 1020) 

Physical Qualities— Average of iy 2 "Rd. 
Untreated 

Tensile Strength 55/65,000 lbs. per sq. in. 

Yield Point 30/40,000 lbs. per sq. in. 

Elongation in 2 * 25/35% 

Reduction of Area 45/55% 

Brinell 130/190 

(All physical properties shown are average, and cannot be guar- 
an teed. Finishing temperatures, permissible variation in analysis, 
and size, each may cause a change in physicals.) 

Forging: 

Quality: POTTS J J is a splendid forging steel, permit- 
ting the forging of most difficult shapes and allowing 
of being drawn down to small dimensions without 
splitting. In these respects it resembles a high grade 
wrought iron like Swedish iron. 

Forging Heat: Ample time must be allowed for a thor- 
ough, soaking heat. At a bright orange or lemon heat 
(1700°) it will work easily, flow well and not open 
surface seams. It can be worked down on one heat to 
small sizes. 

Welding: 

Analysis: Proper and uniform analysis as well as definite 
knowledge of the steel are essential if the welder is 
to secure satisfactory results. You can be assured 
that all sizes of POTTS JJ are practically of the same 
analysis. 

Welding Heat: A white heat (2000°) , not sparkling, is 
proper. Always protect surfaces to be welded with 
borax or any good welding flux. Hammer lightly until 
black cold. 

Bending: 

Because of its high ductility figures (note above elon- 
gation and reduction of area) which are due to its uni- 
formity and well balanced analysis, POTTS JJ will 
stand the maximum of either hot or cold bending 
without fracture.

POTTS JJ— SOFT STEEL 

GUARANTEED DOMESTIC OPEN HEARTH 

Machining: 
POTTS JJ steel has excellent machining qualities. Will 
give a fine finish with freedom from warping, and 
within the limitations of a low sulphur steel cuts clean 
and free. 

Where high sulphur steel of lower strength can be used 
for threading jobs, we recommend THREDWEL 
shown on page 48. 

Heat Treating: 

Responds with certainty to various heat treatments: 
quenching, carburizing, and cyaniding. On request, 
definite methods will be recommended for particular 
purposes. 

Carburizing: 

The most important heat treatment for this class of steel 
is carburizing. The following are recommended, de- 
pending upon the cross-section of the piece to be hard- 
ened, and the purpose for which it will be used:

CROSS-SECTION OF 
RED TOP EXPANDED METAL 



CROSS-SECTION OF 
SHELF-X FLAT MESH STEEL 

Red Top Econo Mesh is a continuous steel fabric of uniformly 
shaped diamond meshes cut and expanded from sheets of open 
hearth steel. It is made in a variety of mesh sizes. Red Top Econo 
Meshes are free from mechanical joints and the strands are made 
clean and smooth by a special deburring process. The sheets can 
be cut in any direction without the strands unravelling. The dia- 
mond mesh pattern adds attractiveness to items of which it becomes 
a part. The meshes are easy to clean and do not obstruct light and 
air. Aside from contributing towards a superior product, Red Top 
Econo Mesh makes possible economies in design and fabrication.

SHELF-X FLAT MESH 

Shelf-X provides many important advantages that are 
not found in wire mesh, wire rods or perforated metal. 



Shelf-X is a workable material. It can be bent in any 
direction and shaped without impairing its strength or 
rigidity. Shelf-X can be readily welded to framing or to 
any material that can be welded. 

Shelf-X because of its flat, smooth surface and the 
small-sized mesh provides a new non-tipping feature. 
Small objects can be slid over Shelf-X without the danger 
of tipping and it therefore lends itself for shelving material 
in Refrigerators, Stoves, Cabinets, etc. Because of the 
flat surface of Shelf-X it is sanitary and easy to keep 
clean. Shelf-X is attractive in design, making it ideally 
suitable for grille work in heating and ventilating units, 
for household utensils and appliances and safety guards.

MECHANICAL 
FLAME CUTTING 

Important economies can now be secured in the field 
of welded fabrication by the use of MECHANICAL 
FLAME-CUT parts. With modern equipment that is 
the latest in capacity, efficiency and speed, we are pre- 
pared to cut any shape of almost any width, length and 
thickness. Our large and varied warehouse stock makes 
selection of the right steel a simple matter and we can 
offer the greatest accuracy in the cutting, no matter how 
intricate the contour. 

A blueprint or sketch of the part needed, with informa- 
tion of the service it is to perform, will enable us to supply 
the proper steel, cut to shape with the minimum of waste. 

Prompt attention given to all inquiries for prices, de- 
liveries, etc. 

Some typical MECHANICAL FLAME-CUT parts are 
shown below! 



1. Union Link, cut"from£l" steel 
plate.

2. Large Ratchet Wheel, dem 

onstrating feasibility of contin 

uous pattern cutting. 




4. Radius Bar for motion work, cut from 5" steel plate. 
5. Side Frame for Press, another low cost and very practical opera- 
tion. 
6. Combination Lever . . . all sides flame cut.

Philadelphia 

REGeut 7450 

Park 5351 



Baltimore 
Vernon 8260 



A new steel developed to meet the demand for a low 
priced material for those jobs where resistance to wear and 
abrasion is of prime importance. 

Characteristics 

A Carbon-Manganese-Silicon type of analysis with a 
normal Brinell of approximately 235 and Tensile Strength 
about 115/130,000 lbs. per sq. inch. WEARTUF is usually 
stocked in this range but can be supplied up to about 
300 Brinell. 



Applications 

Being low in price WEARTUF can be economically used 
for those jobs where the cost of high Manganese Alloy is 
prohibitive. 

WEARTUF will give many times the life of ordinary 
steel and compares favorably with more expensive alloy 
steel. The following are a few of the typical applications: 

Scraper Blades 

Conveyor Buckets 

Liners for Loaders, Mixers, Hoppers 

Shovel and Dipper Lips 

Dredge Pipe 

Dredge Pump Liners 

Sand, Gravel, Coal Chutes, and Screens 

Screw Conveyor Flights 

Truck and Car Bottoms 

Moulds for Abrasive Materials 

Sheathing for Power Shovel Dipper Sticks and Booms 

Cement and Concrete Handling Equipment 

Fabrication 

WEARTUF can be bent, formed, machined and welded. 
Refer application to us for detailed recommendations on 
fabrication. 

Our usual Engineering service stands behind this steel 
and we shall be glad to study your wear and abrasion 
problems. 

We can furnish accurately flame cut to size and shape, 
any size required.

USS COR -TEN 
HIGH TENSILE STEEL 

USS COR-TEN Steel is a ductile low carbon -chromium - 
copper-silicon-phosphorus steel with a minimum yield 
point of 50,000 lbs. per sq. in., and a minimum tensile 
strength of 70,000 lbs. per sq. in. USS COR-TEN is a 
patented steel, and may be welded and fabricated with 
only slight changes in shop practice. Field tests as well 
as actual applications have proved USS COR-TEN'S 
adaptability ... for elevator buckets, coal buckets, mine 
cars, dump cars, railroad cars, trailers, moving vans, 
trucks, buses, street cars, barges, river boats, dredges, 
blast plates, smoke stacks, industrial roofing and siding . . . 
where conditions require a corrosion resisting steel with 
high physical properties.

USS MAN-TEN 
HIGH TENSILE STEEL 

USS MAN-TEN Steel is a copper-manganese steel with a 
minimum yield point of 50,000 lbs. per sq. in., and a 
minimum tensile strength of 80,000 lbs. per sq. in., and is 
used under conditions requiring a steel of high tensile 
strength properties where corrosion is not so important. 
USS MAN-TEN is usually furnished with 0.20 minimum 
copper, giving it atmospheric corrosion resisting properties 
equal to carbon steel with the same copper content. 
USS MAN-TEN may readily be welded and fabricated 
with only slight, if any, modifications in shop technique; 
and this steel has been successfully applied, because of 
its great strength and high abrasion and fatigue resistance, 
to concrete mixer shells and vanes, car dumpers, hoppers 
of dredges and ore boats, heavy duty trail cars, trailers, 
mine cages, stripping shovels, coal vibrating screens, mine 
cars, walking beams of oil well derricks, Tainter and 
Roller gates of dams, crane girders, and many other 
applications.

resist atmospheric corrosion 

Beth-Cu-Loy Copper-Bearing Steel is a 
special grade of refined open-hearth steel to 
which pure ingot copper has been added. The 
special composition of Beth-Cu-Loy makes its 
use highly desirable wherever unusual resistance 
to corrosion is desired. 

In roofing, siding, eave troughs, conductor 
pipe, ventilators, refrigerator linings, furnace 
work, culverts, and in numerous other installa- 
tions exposed to the atmosphere or subjected to 
alternate wet and dry conditions, sheets of 
Beth-Cu-Loy can be depended upon to give 
added years of service. 

Beth-Cu-Loy Sheets not only offer high re- 
sistance to atmospheric corrosion but in addition, 
due to the unified control of all materials and 
processes entering into their manufacture, they 
possess physical properties which make them 
decidedly easy to form and fabricate.

Rust resisting because of Purity. Economical 
because it outlasts ordinary iron and steel sheets 
under conditions which cause corrosion. Easy 
to fabricate and erect because of its ductility and 
good working qualities. 



GALVANIZED SHEETS 

ARMCO INGOT IRON 

Remember — Erection of sheet metal costs 
more in labor than in material. Therefore — 
install ARMCO Ingot Iron because its longer 
life reduces the frequency of the labor cost. 

The galvanized coat on ARMCO is heavy, 
and more free from the microscopic pit holes 
which in ordinary sheets quickly leave the surface 
exposed to RUST. 

Use ARMCO Ingot Iron wherever maximum 
resistance to corrosion is essential. 

For Roofs and Sidings for buildings, sheds, 
garages, etc. For gutters, flashings, down spouts, 
etc. 



HOT ROLLED 

ARMCO INGOT IRON 

The maximum purity makes for longer service 
for Breechings, Stacks, Chutes, Tanks, Boilers, 
etc., Mine Cars, Water and Sewage Pipes, 
Dryers, Heaters, Humidifiers, Gas Tanks, Oil 
Tanks, Stand Pipes, Boiler Jackets and Brine

SURGRIP 

LEAD HEADED ROOFING NAILS 



Base Price 




"Surgrip" Lead Headed Nails require no lead washer 
such as is necessary in other methods of applying corru- 
gated or flat galvanized sheets. Lead Heads hammer down 
tight over the surface of the sheet because "Surgrip" Nails 
are a Unit combining both nail and washer. Application 
is more rapid and joints are tighter and more likely to be 
watertight. 

Made of No. 10 Deformed Wire, corresponding to * 
Standard Roofing Nails. 

Standard lengths l}/£ inches and 2 inches. 

Sold in keg lots of 100 lbs. or in smaller quantities to 
supply any size roofing job. 

We estimate that it requires 21 lbs. of nails to lay 100 
square feet of roofing.

These electrodes can be used in all positions of welding — 
flat, vertical and overhead. With POTTSCO SHIELDED- 
ARC ELECTRODES unusually high operating speeds 
can be maintained. In general, the speed is about twice 
that possible with bare or light-coated electrodes. This, 
together with the ease with which the operator can pro- 
duce a smooth even bead, of full uniform section, means 
high-quality welds at low production costs. 

COATING AND PROTECTION IN WELDING 

The heavy covering on these electrodes is produced by 
extrusion and is of uniform thickness and concentricity. 
This heavy covering protects the. arc stream and the molten 
metal from the oxygen and nitrogen in the air by forming 
a perfect envelope of reducing gases and protecting slag 
on the weld deposit metal back of the crater. 

The type of covering on POTTSCO ELECTRODES 
permits bending the electrodes to a considerable angle 
before the coating will fracture. This is a great advantage 
where certain types of welds require bending the electrode. 
Undercutting is practically eliminated. 

PROTECTION DURING COOLING 

This is a critical stage in welding, and the nature of the 
slag-forming materials contained in the coating and the 
tight envelope they form appreciably slow up the rate of 
cooling. This slow cooling and the exclusion of oxygen 
and nitrogen give a dense fine grain structure, free from 
gas holes or inclusions. Shrinkage stresses are thus reduced 
and the ductility increased. 

REMOVING PROTECTIVE FORMATION 

The complete slag formation on the weld metal, after 
cooling, requires the minimum effort for removal. Usually 
"by tapping the parent metal adjacent to the weld metal 
the slag covering comes off intact for part or all the length 
-of the bead.

TECHNIQUE OF WELDING 

Every welder is familiar with the fact that air in con- 
tact with hot weld metal seriously affects the weld. Air 
contains oxygen and nitrogen and with ordinary methods 
and uncoated welding rods there is nothing to counteract 
the effect of these two gases on the hot weld metal. The 
two cuts on this page illustrate protected and non-pro- 
tected welding. Research has shown that if thejmolten 
weld metal is protected from the air while being deposited, 
the injurious effects of these gases are eliminated.

POTTSCO No. 107 Electrodes absolutely afford the 
necessary protection for a superior weld. POTTSCO No. 
107 Electrodes have three main features; 

1. The coating burns slower than the metal elec- 
trode, thus forming a projection which shields the 
heated end of the electrode metal. 

2. The burning of the coating forms a gas which 
surrounds the molten weld metal and excludes all 
atmosphere. 

3. A protective slag coating forms over the deposited 
metal and excludes the oxygen while the weld is 
cooling and also retards the rate of cooling.

FEATURES 
SERVICES 

POTTSCO No. 107 is a mild steel general purpose 
electrode of the shielded-arc type, producing welds of ex- 
ceptionally high strength and ductility. Especially recom- 
mended for high speed single pass welding. 

THREE POSITION 

POTTSCO No. 107 Electrodes are suitable for use in 
flat, vertical or overhead welding. See pages 87-91 for 
operating instructions. 

SPEED 

The shielded-arc type of welding requires much higher 
voltage and amperage than for the unshielded- arc but the 
resulting increase in heat makes it possible to weld much 
faster. There is an exceptionally smooth bead and very 
low spatter loss. 

QUALITY 

The weld metal in welds made with POTTSCO No. 107 
Electrodes has tensile strength, elongation, density, 
fatigue and impact resistance equal or better than mild 
steel. See figures on page 84. 

COATING 

POTTSCO No. 107 Electrodes have a heavy flux 
coating which is of uniform thickness and composition. 
This coating will not crack nor spall off from ordinary 
handling.

GENERAL OPERATING INSTRUCTIONS 

POLARITY 

POTTSCO No. 107 ELECTRODES should be used 
with regular polarity, that is, the electrode connection 
negative and the work connection positive. 

LENGTH OF ARC 

Use a short arc about the same as used when welding 
with a bare electrode. However, the arc length should 
never be so short that the coating touches the molten pool 
as this would tend to cause a porous weld. 

ELIMINATING CRATERS 

At the completion of the weld or when changing elec- 
trodes, craters can be eliminated by withdrawing the 
electrode slowly at right angles until the arc is broken. 

METHOD OF STARTING 

When starting another electrode, strike the arc slightly 
ahead of the crater, hesitate for a moment, then move 
backwards to completely remelt and fill the crater. Pro- 
ceed as usual. 

WEAVING 

When weaving is specified use the motions indicated in 
the diagram below. Stop for a moment at sides of scarf.

GENERAL OPERATING INSTRUCTIONS 

(Continued) 

PREVENTING UNDERCUTTING 

Undercutting can be prevented by watching the solidify- 
ing metal and advancing the arc at a rate which will fill up 
all of the undercut. Do not advance the arc too rapidly. 

COATING ON DEPOSITED METAL 

POTTSCO No. 107 ELECTRODES form a slag 
coating on the deposited metal. This coating protects the 
deposited metal from the air until it cools, and also retards 
the rate of cooling, thus providing a beneficial annealing 
effect. It can be removed quite easily after it cools with 
any blunt tool and wire brush. This should be done 
(especially along the edges of the weld) before proceeding 
with a new bead* 

ARC BLOW 

Arc blow will cause an uneven burning of the coating 
and result in improper fusion and gouging in the side 
walls. When present, arc blow can be frequently com- 
pensated for by shifting the ground connection to a dif- 
ferent part of the work. 

FITTING UP 

It is always worth while to take the time necessary to 
secure a proper alignment of the parts that are being 
welded. It will pay in better welds and greater welding 
speed. 

HEAT DISSIPATION 

Always direct the arc in such a manner that both plates 
are heated equally, especially when welding plates of 
unequal thickness. 

SET UP 

Work should be arranged so that the molten pool will be 
as near horizontal as possible. This can usually be ac- 
complished by tilting the work at a slight angle. Increased 
welding speeds will result. 

ALLOW WELD TO COOL 

Welds should be allowed to cool between beads. On 

heavy plates and long seams the weld will usually cool 

sufficiently as the operator proceeds, before the next bead 

is applied, but sometimes in short heavy sections this 

will not happen and additional time must be allowed. 

The cooling will also make it easier to remove the slag 

coating.

Either narrow or wide beads may be deposited without under- m 
cutting at the sides of the bead by holding a rather short arc,* 
i.e., with the coating just out of contact with the molten crater. 
The electrode should be inclined about 20° in the direction oim 
travel. — 

A light but complete slag covering is left on the bead but the 
crater is free from slag, making it easy to resume operation m 
after any interruption to the arc. * 

In multiple bead welding the slag must be removed thoroughly 
by scaling with a chisel or other pointed tool before the next* 
layer is applied. The slag is removed easily when cool. Failure" 
to observe this precaution may result in porosity. 

It is advisable not to apply the second layer until the first isaj 
cool to the hand. 

FILLET WELDS 

Use current values shown in table (page 87). Incline the elec-( 
trode at an angle of about 45° with the horizontal member. A 
short arc should be maintained and the electrode advanced in a 
steady, straight line without weaving or retracing. This willQJ 
produce a bead of uniform section with full throat and equal 
areas of fused contact on both vertical and horizontal members. 

LAP WELDS ■ 

The procedure is the same as for fillet welds. _ 

VERTICAL WELDS 

(Welding Down) 

In vee or fillet welds use %" or %* electrodes at currents^ 
shown in table (page 87). The arc length should be somewhat 
greater than for flat welding. The electrode should be inclined™ 
upward at an angle of about 15° and should be advanced in aP 
straight line without weaving. Multiple beads may be applied 
as needed to produce the section of weld desired. 

Slag may be removed by scaling but in vertical down welding™ 
it is often possible to melt away the slag by the application of the 
second layer. In this case, the arc should be held stationary for » 
few seconds to clean the crater after which the electrode should 
be advanced. The operator should see that all slag is melted 
away well ahead of the crater. When welding is interruptedj| 
slag accumulations should be removed by scaling. In this method 
a fairly high value of welding current should be used. 

VERTICAL WELDS C 

(Welding Up) 

Welding up is required in certain applications, notably by th^ 
U. S. Navy, and while greater skill is required from the operator" 
in general, strong, dependable welds will be produced. The slag 
must be removed carefully by scaling and each bead should be" 
allowed to cool before the second layer is applied. Light peemnfP 
of each bead will aid materially in removing residual stresses. 

The currents recommended in table (page 87) are consider" 
ably lower than for flat or down vertical welding. In general, %" 
to % '-diameter electrodes should be used. The electrode should 
be held at nearly right angles to the work and advanced in £* 
straight line without weaving or retracing.

VERTICAL WELDS 

(Butt Seams) 

Welds of this type should be made "welding up" with M% f - % /i^ 
iectrodes with currents shown in table (page 87). The width 
f the bead and depth of the throat should be regulated to meet 
ie requirements of the work. 

OVERHEAD WELDS 

These welds should be applied in numerous light beads using 
V-Hi" and % * electrodes at current values shown in table 
rith a short arc. Slag should be removed carefully by scaling and 
eads allowed to cool before the additional layers are applied. 

Note — In the use- of the POTTSCO No. 107 ELECTRODES, 
lie tendency for undercutting at the sides of the seam and spatter 
)ss will be reduced to a minimum. The efficiency of the electrode in 
oth of these respects depends to a considerable extent on the 
maintenance of the correct length of arc and on the amount of 
relding current used. Operators should check these points 
are fully.

POTTSCO No. 15 
"CASTALOY" ELECTRODES 

A hard surfacing electrode manufactured especially for Horace T. 
Potts Co. It is an iron base alloy. The weld deposit is air hardening 
and can be applied only by the electric arc process — either the 
metallic arc or the carbon arc method. It does not possess great 
hardness at high temperatures — see COLMONOY No. 3, page 98, 
for this quality. Over a period of years it has given excellent results 
on mining equipment for crushing rock, ores, etc. It is used ex- 
tensively in the cement industry for all wearing parts— grinding 
rings, plows, rolls, conveyor flights, hammers, crusher rolls, gud- 
geons, bucket lips, drag link chains, etc. Other applications are: 
pug mill paddies, wet ash-pump casings, and impellers. Used as an 
outside layer over the manganese deposit, after building up worn 
manganese dipper teeth, POTTSCO No. 15 gives additional wear; 
but its main function is the protection of the built-up manganese 
deposit until it receives the cold working necessary to improve its 
wearing qualities.

WELDING TECHNIQUE 

POTTSCO No. 15 requires reverse polarity and the arc charac- 
teristics are similar to those of all non-ferrous electrodes. The 
recommended current (amperes) and arc voltage are about the 
same as for a mild steel electrode for general purpose welding. 
Like all other high Brinell deposits, it is inadvisable to build up a 
thick overlay, as high hardness is almost always associated with 
brittleness. Where the equipment requires a large build-up use 
either POTTSCO No. 45, page 97, or POTTSCO No. 29, page 94, 
according to the impact the piece of equipment receives, and then 
finish off with one or two layers of POTTSCO No. 1 5 for abrasion 
resistance. 

BRINELL HARDNESS— The hardness number of the deposit 
metal has shown as high as 650, the average being 500. 

POTTSCO No. 15 is an outstanding hard surfacing electrode 
that will meet average abrasion resistance requirements and at a 
cost but slightly higher than a good general purpose mild steel 
electrode.

(Page Flux Coated High Carbon Electrodes) 

Light flux coated (dipped) electrode having same use as bare 
POTTSCO No. 11 but with greatly improved arc stability. It 
gives a non-porous deposit due to the protection from the coating. 
Welds made with bare electrodes with carbon content above .70% 
tend to be porous due to the violent reaction to the atmosphere 
and the high carbon content in a high temperature arc, which 
liberates carbon gases in deposited metal, leaving a honey-comb 
surface in the weld metal. The flux coating eliminates this and has 
the additional advantages as set forth under POTTSCO No. 39, 
page 94.

POTTSCO No. 47 

(Stulz-Sickles Co.— Bare Manganal Electrodes) 

These electrodes are manufactured by a special process which 
results in a weld deposit metal that is tough and hard, and free 
from checking. 

POTTSCO No. 47 ELECTRODES give high tensile strength 
and ductility. By hardening under impact, abrasion resistance 
equal to the parent metal is secured. 

Welding heat tends to impair the useful qualities of Manganese 
Steel, but in POTTSCO No. 47 ELECTRODES the low carbon 
and 3% Nickel content help to correct the brittkness in the ad- 
jacent parent metal and give toughness in the weld deposit. 

Quenching is not necessary, but peening, if done while weld 
metal is hot, will give improved results, taking care of contraction 
and building up surface hardness. (Peen thoroughly but not ex- 
cessively.) 

This electrode is furnished either bare or flux coated. 
Applies tions : 

Used for building up high manganese steel parts such as bucket 
lips, dipper teeth, grinding rolls, and railway track work such as 
frogs, switches, crossovers, etc. The most satisfactory rod for 
reclaiming worn manganese steel castings, and equally effective

POTTSCO No. 51 

(Carbon Electrodes) 



A CARBON ELECTRODE having a low ampere carrying ca- 
pacity and extreme hardness. They will hold to desired tapers and 
will not spindle unevenly, assuring exceptionally long life. Recom- 
mended for normal amperage. 

POTTSCO No. 53 

(Carbon-Graphite Electrodes) 

CARBON-GRAPHITE ELECTRODES are a combination of 
high grade carbon and graphite which produces an electrode softer 
than pure carbon but having a higher ampere-carrying capacity. 
Recommended for intermittent service on high amperage, especially 
for cutting. 

POTTSCO No. 55 

(Pure Graphite Electrodes) 

PURE GRAPHITE ELECTRODES are fully graphitized in an 
electric furnace. They are unexcelled where high amperages and 
resultant high temperatures are required and will operate efficiently 
in continuous service. They give much longer life under severe 
operating conditions than the CARBON ELECTRODES or 
CARBON-GRAPHITE ELECTRODES. 

Use straight polarity. 

POTTSCO No. 31 

(Aluminum— 5% Silicon Electrodes) 



A shielded-arc type electrode, 
cast and sheet aluminum. 

Recommend reverse polarity. 



Used for metallic arc welding of 



POTTSCO No. 45 

(Page Shi elded- Arc Armco Electrodes) 

One of the best electrodes for making strength welds in cast iron. 
May be used for welding steel and has the advantages of POTTSCO 
No. 7 ELECTRODE with somewhat greater ductility, but with 
lower tensile strength because of its low carbon content, .012%. 

Recommend reverse polarity, but straight polarity may be used. 

POTTSCO No. 49 

(Page Hard Facing Welding Rod) 
WHAT THEY ARE 

POTTSCO No. 49 HARD FACING WELDING RODS consist 
of a balanced composition of nickel, chromium, tungsten, molyb- 
denum and tungsten carbide. 

May be used with either oxy-acetylene torch, electric arc or 
atomic arc welding processes for hard facing all grades of steel, 
gray iron or malleable iron. 

PENETRATION 

Any welding method will produce a perfect bond of deep pene- 
tration and the hard surface will not spall off. 

TOUGHNESS 

The hard facing produced by these rods has great shock-resisting 
properties. 

ABRASION RESISTANCE 

This unusual combination of toughness and hardness is due to 
the locking of tungsten carbide particles in the matrix of the alloy. 
At temperatures from 1150 degrees F. up to 1500 degrees F. welds 
made with this rod retain their resistance to wear.

COLMONOY ALLOYS 
AND OVERLAY METALS 

COLMONOY products contain certain heretofore unknown 
metallic crystals. These crystals are insoluble in hot or cold acid or 
alkali solutions, do not oxidize even at high temperatures, have a 
hardness of approximately 9 on Moh's scale and retain their identity 
when they come in contact with fused metals. 

COLMONOY crystals may be applied or sweat-on with the 
flame of the oxy- acetylene torch or the carbon electric arc, and 
may be applied to the vertical as well as the horizontal plane, or 
overhead. Furnace heat may be used where feasible. They may be 
made to follow any contour or shape and may be applied in a con- 
tinuous layer or in spots or well defined areas. Regardless of the 
method or type of application, the more common metallic boride 
crystals alloy with the skin or outer surface of the parent metal to 
form a matrix for the COLMONOY crystals which do not fuse 
or unite with each other, so that the parent metal, although well 
protected, is free to expand or contract or change its form by form- 
ing or forging without disturbing the overlay. 

SWEAT-ON 

Crystals shipped in 1 lb. and 
5 lb. containers. 

Paste furnished in 1 lb. triple 
sealed top tin cans or in small size 
tubes. 





COLMONOY WELDING 
RODS AND ELECTRODES 

By mixing various quantities of COLMONOY crystals with 
certain base metals and alloys, welding rods and electrodes have 
been prepared, which can be used with ferrous metals in the usual 
ways to form wear-resistant, welded-on overlays or hard facings. 
These rods are designated by number, each designed for a specific 
use or class of uses, and will be found very easy to apply with 
either the oxy-acetylene torch or the metallic electric arc, resulting 
in a solid, efficient overlay that is well amalgamated with the 
parent metal. 

COLMONOY No. 1 

A high carbon steel core material with a flux coating made up of 
COLMONOY crystals, particularly adapted to building up rela- 
tively large sections or thick overlays. Results in hard, tough 
deposits of 60 or more Rockwell C with considerable inherent 
strength. For gas or electric arc (reverse polarity) application. 

COLMONOY No. 2 

A cast rod forming a very efficient wear-resistant surface on 
ferrous metals at a relatively low cost. Give a quite hard (58 Rock- 
well C) deposit suitable for average requirements not subjected to 
severe shock or pounding. 

COLMONOY No. 3 

A cast rod showing resistance to shock and abrasion and possessing 
considerable red hardness. Rockwell C approx. 64. 

COLMONOY No. 6 

Forms a deposit having a Rockwell C hardness of 58 to 60 which 
is highly resistant to sulphuric acid as well as exceptionally resistant 
to abrasion. Grinds to a smooth polished surface and also wears 
smooth in service. For gas and electric arc application.

POTTSCO STAINLESS AND 
HEAT RESISTING 
ALLOY STEEL 
ELECTRODES 

(Page-Allegheny) 

A shielded-arc type electrode for welding stainless steel. The 
heavy covering on these electrodes is produced by extrusion and 
is uniform throughout their entire length and kept at a definite 
micrometer thickness for each size. This assures the same free 
flowing and quiet arc characteristics in every electrode. It also 
forms a perfect slag covering of uniform thickness over the de- 
posited metal. This protection is of the utmost importance in the 
welding of stainless steel. It requires the minimum amount of 
labor for the removal of this slag. The composition of core material 
or rod is of the low carbon range with the proper percentage of 
chromium or chromium and nickel to guarantee the maximum 
non-corrosive qualities in the weld deposit. 

Recommend reverse polarity. 

POTTSCO STAINLESS STEEL ELECTRODES can be sup- 
plied in all standard analyses. The following paragraphs describe

This type is used perhaps more than any other electrode for 
welding on Stainless Steel. It is a corrosion-resistant steel for the 
widest range of applications. It makes a weld which is resistant 
to atmospheric or other moisture, salt water, milk, foodstuffs and 
most organic or inorganic chemicals; and one that will machine 
readily and take a high polish. 

This electrode contains approximately 19% Chromium and 9% 
Nickel, with a very low Carbon content. Heat treatment after 
welding is not always necessary, and where it is employed, does 
not harden the weld metal. 

POTTSCO 19-9 S can also be furnished with TITXNIUM or

POTTSCO FUMELESS BRONZE 

A bronze welding rod of patented analysis for all general gasl 
welding. We recommend this rod for all bronze and copper 
alloy welding as well as for steel and cast iron. Its low melting 
point and free-flowing characteristics make it exceptionally easy I 
to use. This rod will produce welds of high tensile strength 
(see above) with excellent wearing qualities. 

POTTSCO FUMELESS BRONZE, due to the dioxidizingl 
agents included in the patented analysis, produces a sound, 
gas-free weld. No objectionable fumes are given off, making a 
most satisfactory rod from the viewpoint of the welder. 

Many shops stock this one grade for all their bronze work, 
thus saving inventory costs.

POTTSCO 200-HOUR | 
COVER GLASS 

In the process of electric arc welding there is rapid bombard- 
ment of the cover glass by minute molten particles of metal 
These molten particles fuse into the ordinary clear cover glass | 
often making it necessary to change this glass once or twice 
every eight hours of actual welding.

ACCO SLING CHAINS 

MADE BY 

THE AMERICAN CHAIN DIVISION OF 

AMERICAN CHAIN & CABLE CO. 

These slings are made from H.B. or AJAX Iron Dredge 
Chain as specified. Hooks, rings and joining links are of 
such size that they will withstand a load equal to the 
strength of the chain on which they are used. Sling Hooks 
are drop forged and designed so the load line will pass 
directly through the center of the bowl and eye of the 
hook. Welding is entrusted only to workmen who have 
had many years' experience, thus insuring perfect welds. 

H.B. Chain is made from single refined, all puddled 
iron, without admixture of iron or steel scrap. AJAX 
Chain is made from double refined, all puddled iron, 
without admixture of iron or steel scrap. Both H.B. and 
AJAX grades will meet A.S.T.M. specifications for iron 
crane chain. See the latest A.S.T.M. specifications, 
Designation A-56, for details of manufacturing and physical 
and chemical requirements. 

Complete prices and engineering data will be furnished 
on application. 




STYLE D Double sling chain with Ring and Sling 
Hooks. Sling Chains may be furnished with Pear Shaped 
Link and Grab Hooks if so specified. 




STYLE S Single sling chain furnished with Ring and Sling 
Chain Hook. Pear Shaped Link and Grab Hooks will be 
furnished when so specified. 

NOTE: Orders should specify type fittings wanted and 
bearing to bearing length which includes attachments.

MACWHYTE SLINGS 

SINGLE AND MULTIPLE-PART 




Close up view of body types shown on page 116. 

The great variety in size, shape, and kind of materials 
handled with slings, requires a wide range of types to meet 
the individual conditions. There is practically no kind of 
work needing slings that cannot be handled with maximum 
safety and economy by the various types of Macwhyte 
Single and Multiple-Part Wire Rope Slings. 

There are three kinds of sling bodies available — 
ATLAS, DREW, and MONARCH. 

The ATLAS Slings are made of two endless wire rope 
elements braided to form a sling body with extreme flexi- 
bility and maximum strength. They are non-kinking, non- 
spinning, and remain highly flexible throughout their life. 

The DREW Slings are made of one wire rope endless 
element braided to form a sling body having multiple 
parts of wire rope which increase its flexibility and make a 
high strength flat sling. Its light weight facilitates at- 
tachment to crane hooks and the flat surface gives good 
bearing for material handled. 

The body of the Macwhyte MONARCH Sling consists 
of a single Monarch Whyte Strand Wire Rope, the strong- 
est of hoisting ropes. It is used where flexibility is not a 
prime requisite. 

Catalog on Macwhyte Single and Multiple-Part Wire 
Rope Slings will be furnished on request.

MACWHYTE 
PREFORMED 

WIRE ROPE 




Macwhyte Company manufactures both PRE- 
FORMED and non-preformed wire rope. 

In Macwhyte PREFORMED wire rope, the wires and 
strands are formed in the helical shape they take in the 
finished rope, as shown in above photograph. 

The wires lie naturally in place, internal stress and fric- 
tion is reduced to the minimum. Fatigue-resisting quali- 
ties are increased, thus giving longer and better service. 

Macwhyte PREFORMED wire rope is safer to handle 
because wires broken from wear lie flat against the rope 
instead of wickering out. 

Improved service is given especially Where bending is a 
factor, such as in excavating, mining, rotary drilling 
logging, quarrying, etc. Send for special descriptive 
folder "The WHY in MacWHYte PREFORMED Wire 
Rope." 

Whenever you are in doubt as to whether you are order- 
ing the best wire rope for your particular use, just tell us 
what kind of equipment you are using, the work being 
done, and we will be glad to recommend the best rope 
for your use. 

Macwhyte Wire Rope is carried in stock for prompt 
delivery. 

PROPER WORKING LOAD 

It is never advisable for the working load of a wire 
rope for general purposes, particularly running ropes, 
to exceed one-fifth of the breaking strength. This means 
that the factor of safety should be not less than five. 
To determine proper working load, divide the breaking 
strength by the proper factor of safety, e.g., a %» diameter 
x 19 Plow Steel Rope has a breaking strength of 28 
tons and with a factor of safety of five the proper working 
load would be not over 5.6 tons.

MACWHYTE STANDARD 
HOISTING ROPE 

6x19 

"Standard Hoisting Rope" is a term generally applied 
to wire rope having 6 strands, 19 wires to the strand, with 
one hemp core. It is made in various wire constructions 
and grades to suit individual operating conditions.

MACWHYTE 
INTERNAL LUBRICATION 

Through proper lubrication, Macwhyte Internally 
Lubricated Wire Rope resists internal rust, corrosion, and 
friction; the inside wires are usually in excellent condition 
after the outside wires are worn through and have given 
maximum service. 




An ideal lubricant must 
protect the inside bearing 
surfaces of the wires by filling 
the spaces between them. It 
must keep out moisture, and 
resist ordinary acids. It must 
be a tenacious, heavy substance that will cling to the 
wires unaffected by the hottest or coldest climatic 
temperatures. 

Such is the lubricant used in Macwhyte Wire Rope, Be- 
cause it retains its heavy consistency, even when heated to 
more than "'200°, it must be pumped by a special machine, 
invented at Macwhyte Company for the purpose. 

You can have Macwhyte Internal Lubrication in either 
PREFORMED or Non-Preformed Ropes with no extra 
charge. Samples of Internally Lubricated and PRE- 
FORMED Wire Ropes will be furnished on request. 

Macwhyte Internal Lubrication is one of the two visible 
outstanding improvements in wire rope in many years. 
PREFORMING is the other. For more complete infor- 
mation send for special circular " Macwhyte Internal 
Lubrication." 

Complete catalog and prices will be furnished upon 
request.

MACWHYTE 



MACWHYTE SPECIAL TRACTION 8x19 (SEALE) 



Macwhyte Special Traction Elevator Rope is the 
original Special Traction, and, as the name indicates, is 
built especially to meet the exacting conditions found on 
the modern traction types of high speed elevators. 

It combines great toughness and flexibility and con- 
tains an arrangement of wires (strand construction) that 
produces a maximum of wearing surface. 

It contains two more strands than the ordinary 6 x 19 
hoisting rope and 33% more points of contact on the 
sheaves. The two extra strands add much to the flexi- 
bility, and the additional points of contact greatly in- 
crease the traction between the rope and the driving 
drums. In addition the rope will stand more abrasive 
wear, which is an important factor on passenger and 
freight elevator work. 

Macwhyte Special Traction Elevator Rope on U and V 
groove traction elevators will give excellent service. It 
will withstand abrasion for long periods because of the 
comparatively large wires on the outside. 

For complete list of warehouse stock sizes of elevator 
ropes: page 103.

metal for use on Textile Machinery, Printing and Paper 
Making Machinery, Stationary Hoisting and Traction 
Engines, Woodworking Machinery of every description, 
Pumps, Cotton Gins and Compressors, Brick Machines, 
Stone Crushers, Agricultural Machinery and for general 
Machine Shop Work. 

"PERFECTION" Anti-Friction Metal provides the 
following advantages: 

1. It has a low melting temperature. 

2. It can be repeatedly remelted without deterioration. 

3. It remains in a molten state longer than most bearing 
metals. 

4. It flows freely, completely filling all parts of the bearing. 

5. It will stand up under the heaviest loads, yet is so soft 
that dust and grit will become imbedded in the metal 
instead of remaining on the surface and scratching the 
shaft or spindle. 

6. It has a minimum fractional coefficient. 

7. It requires the least amount of oil for proper lubrication. 

8. Its shrinkage is reduced to the minimum. 



FRICTIONLESS METAL 

FRICTIONLESS Metal is a true Anti-Friction metal 
of merit. It is of Lead base, toughened with Tin and hard- 
ened with Copper, and has a low coefficient of friction. 
For general railroad and machine shop purposes, it is un- 
excelled. FRICTIONLESS is almost universal in its appli- 
cation, and will stand high speeds and severe service. It is 
internationally known, and carries a guarantee of satis- 
faction. 

Used by Saw and Planing Mills; Mining and Brick 
Plants; Paper, Flour and Cotton Oil Mills; Machinery 
Manufacturers.

The very extensive and successful use by industry, for 
the past twenty -five years, of our ELASTUF Machinery 
Steels has caused the name "ELASTUF" to be recognized 
as "A Standard" of Quality'* in carbon and alloy machine 
steels. The results of our close observations of this wide 
application of ELASTUF Steels during this time have 
been carefully recorded, compared, and analyzed. This 
invaluable data, combined with extensive research 
facilities, has resulted in the present high manufacturing 
standards peculiar to ELASTUF Machinery Steels. 

A few of these many refinements are: careful selection of 
heats, close chemical control, heavy discards on ingots 
and blooms, and frequent etched disc inspection; all of 
which tend to eliminate faulty steel. 

Accurate control of temperatures during manufacturing 
operations of the untreated stock, and with the heat 
treated bars the most exacting methods as to time, tem- 
perature, quenching and drawing, give our ELASTUF 
Steels remarkable freedom from distortion in machining 
operations. 

McQuaid Ehn grain size control is employed on all 
ELASTUF Steels to improve machinability and response 
to heat treatment. 

When you specify any of the ELASTUF Steels you 
have the confidence of knowing that your costs of labor 
and installation are being put on a steel which is as nearly 
perfect as human ingenuity can produce. 

All the quality refinements of ELASTUF Steels are 
available to you at no extra cost. It is to your advantage 
to specify and insist upon ELASTUF Steels in either 
standard S.A.E. or special analyses.

Analysis: ELASTUF PENN is a special 
analysis, approximately .40 C. steel of the 
Manganese type, without Chromium. While, 
because of its analysis, it might be called an 
alloy steel, we avoid the use of the term, class- 
ing an alloy steel as one containing appreciable 
quantities of one or more of the alloying ele- 
ments of Chromium, Vanadium, Nickel, 
Molybdenum, etc. 



3q 

2C 



Quality: Made under accurate quality control, 
thus assuring a clean steel of uniform struc- 
ture. Free from all mechanical defects such as 
seams, pipes, "laps, etc. Manufactured under 
Grain Size Control. Useful for a wide variety 

I of purposes calling for maximum strength 
short of that of heat treated alloy steels. 

I 

Finish and Straightness: Hot rolled finish. 
| All bars machine straightened. Can be used in 

automatics. Can also be furnished Cold 
- Drawn, Turned and Polished and Turned, 

Ground and Polished. 



Machining Operations: Outstanding char- 
acteristics of ELASTUF PENN are its free 
machining qualities and its ability to take a 
fine finish. It is easily machined without 
annealing. Special processing minimizes 
strains, and thus distortion or warping in 
machining hot rolled bars is rare. ELASTUF 
PENN cuts freely, without tearing, on all 
operations of turning, milling, threading, 
boring, reaming, etc., and on turrets and 
automatics. 

Comparison of Grades: Because of its higher 
physical properties and better machinability, 
compared with plain carbon steels and un- 
treated or annealed alloy steels, it may be 
used in place of the following untreated or 
annealed steels, viz.: 

■S.A.E. 1040, 1045, 1050, 1340, 1350, 3130, 3135, 3140 f 
3145, 3150, 2330, 2335, 2340, 2345, 2350, 4130,

All physical properties shown are average and cannot be 
guaranteed. Finishing temperatures, permissible varia- ■ 
tion in analysis and size, each may cause a change in' 
physicals. 



Heat Treatment: Controlled quality in ELASTUF I 
PENN insures excellent response to heat treatment, 
with minimum distortion. 

We recommend oil quenching at temperatures varying 
from 1550° F. to 1600° F., depending on mass. Thorough 1 
heating to allow for complete change of structure is 
important. , . 

Quenching baths must be ample in size. Drawing 
temperatures will vary with the purpose. For gears,! 
worms, pinions, etc., we suggest 500° F. For shafts,* 
axles, etc., we suggest 1100/1200° F. Machined parts, 
such as gear blanks, may be hardened to 50/60 Rock. C.|

Carburizing: ELASTUF PENN may be car- 
burized for specific purposes and responds 
readily to proper treatment. Consult us as to 
methods. 

Water Hardening: Water hardening with 
ELASTUF PENN may be done with safety 
only with great caution, and with careful con- 
sideration of details of piece to be hardened. 
The effect is to increase hardness greatly, 
with much higher tensile and elastic limit, but 
with a considerable loss of ductility and ten- 
dency to brittleness. 

Forgings: All sizes and shapes can be supplied 
promptly from ELASTUF PENN forging 
billets carried in stock. 

Heat Treated Bars and Forgings: We can 
furnish all sizes in bars and forgings heat 
treated to meet customers' requirements.

ELASTUF S.A.E. 3140 

CHROME NICKEL ALLOY 
MACHINERY STEEL 

HEAT TREATED 

This grade is the same as described on page 132 under 
Hot Rolled except that bars are Heat Treated to definite 
physical properties. These properties, as listed on page 124, 
are not the average of a 1" round sample but are the 
actual physicals to be expected from each range of sizes 
shown. This grade is useful for highly stressed parts where 
the physical properties of ELASTUF PENN Machinery 
Steel (see page 126) are insufficient, and where the higher 
strength and greater toughness of ELASTUF TYPE A 
Heat Treated are not needed. It is readily machinable.

ELASTUF CHRO-MOLY 

ALLOY MACHINERY STEEL 
HEAT TREATED 

Analysis: A Chrome Molybdenum Alloy Steel, with 
elements so proportioned as to give the best combination 
of physical properties and good machinability in the 
heat treated condition. 

Sizes up to and incl. 4" Rd 35/.4S Car. 

Sizes 434 " Rd. and Larger 45/.S5 Car. 

Characteristics: elastuf chro-moly re- 
sponds favorably to heat treatment, resulting in a steel 
of wide applicability, at moderate cost. In the heat 
treated condition it has a high yield- tensile ratio, it is 
readily machinable even in automatics, and has high 
impact values. It is not susceptible to temper brittle- 
ness, consequently the rate of cooling from drawing 
temperatures has little effect on the impact properties. 

ELASTUF CHRO-MOLY retains its physical proper- 
ties at elevated temperatures and fully meets A.S.T.M, 
Specification A-96-33, Class "C" for high temperature 
bolting material. This steel possesses marked creep 
strength or resistance to creep at high temperatures. 

ELASTUF CHRO-MOLY has the maximum physical 
properties obtainable with this type of steel. The prop- 
erties shown on the following page are not the aver- 
age of a 1 * round sample, but are the actual physicals 
to be expected from the range of sizes shown. 

First Cost: Assuming that a number of steels have 
physical properties that make them equally fit for a 
given service then, and only then — first cost becomes a 
matter well worth consideration. ELASTUF CHRO- 
MOLY Heat Treated is a steel of quite moderate cost. 

Uses: The real value of a heat treated alloy steel is in 
the service obtained, with due consideration given first 
cost and fabrication expense. ELASTUF CHRO- 
MOLY Heat Treated has a wide range of applications 
for highly stressed parts where the physical proper- 
ties of ELASTUF PENN Machinery Steel are insuffi- 
cient and where the high strength and great toughness of 
ELASTUF TYPE A HEAT TREATED are not 
needed. A partial list of applications is : gears, pinions, 
shafts, axles, spindles, crank shafts, steering knuckles 
and arms, piston rods, oil well reamers, motor parts, 
etc. Because of its resistance to creep, this grade is 
excellent for high temperature and high pressure studs 
and bolts and other parts. 

Machining: (Heat Treated Stock Bars) First cuts 
should be light to minimize warping and care should 
be taken to obtain the proper relation of feeds, speeds 
and cuts. It is necessary to reduce speeds and feeds 
as compared with straight carbon steels, ELASTUF 
PENN, or annealed Alloy Steels. Tool marks should 
be carefully avoided, key ways and all shoulders should 
be generously filleted. 

rorgtngS: Special shapes can be supplied promptly, 
heat treated to standard or special requirements.

ELASTUF TYPE A 

ALLOY MACHINERY STEEL 
HEAT TREATED 

Analysis: A special Chrome Vanadium Steel 
with elements so balanced as to give the most 
desirable and uniform combination of physical 
properties. 

Rds. up to 2 " incl .\~ %A ft _ , „„ _ . 

Sqs., Hexs. and Flats jTemper 14-.25/.35 Carbon 

Rds. 2%" and Larger Temper 9— .4S/.55 Carbon 

Characteristics: High Strength, great tough- 
ness, exceptional elasticity and wear resist- 
ance. 

ELASTUF TYPE A in the heat treated condi- 
tion meets the demand for a steel of maximum 
strength, which is at the same time machin- 
able. It has more than three times the 
strength of soft steel, and is highly resistant 
to abrasion, shock and dynamic fatigue. Will 
withstand alternating and repeated impact 
stresses to a marked degree without fatigue ' 
failure. 

ELASTUF TYPE A, Heat Treated, has the ( 
maximum physical qualities consistent with i 
good machinability. This ease of machinability 
makes it valuable for many purposes requiring j 
maximum strength, particularly where heat 
treatment after machining is neither feasible | 
nor economical. 

The high physicals of the heat treated stock ! 
are well illustrated by the figures given for 
each range of sizes on the following pages. | 
These properties are not the average of a T 
round sample, but are the actual physicals | 
to be expected from the sizes shown. 

ELASTUF TYPE A, Heat Treated, is particu- 
larly recommended for heavy duty shafts and 
axles carrying extreme loads and with excep-l 
tional heat, wear, shock and fatigue conditions u 
present.

Uses: Recommended for bolts and studs on high 
pressure and high temperature oil and steam 
lines; fan shafts, crank pins, conveyor shafts, 
steam shovel shafts, crusher roll shafts, pump 
drive shafts, dredging machine shafts, crank 
shafts, locomotive axles, propeller and arma- 
ture shafts; bolts for textile machines, motor 
frames and gas retort doors, gears, worms, 
pinions, etc. 

Forgings: Special shapes, large gear blanks, 
shafts, etc., can be supplied promptly, heat 
treated to requirements. Unless specified to 
the contrary, all forgings are heat treated to 
approximately 302/340 Brinell, in which con- 
dition they can be machined and put into 
use without further heat treatment. 

ELASTUF TYPE A, Heat Treated, should not 
be welded by any method, nor should it be 
forged or heated above a dull red, as by so 
doing the beneficial properties resulting from 
heat treatment are lost. 



Machining: (Heat Treated Stock Bars) Since 
high physicals are of prime importance, all 
stock bars, except annealed, are heat treated 
to produce maximum strength and still be 
machinable. By using somewhat reduced 
speeds and feeds, compared to those usual with 
untreated carbon steel, machining operations 
can be done on ELASTUF TYPE A, Heat 
Treated, without difficulty. In machining, first 
cuts should be light; to minimize warping. The 
tool should be so ground that it cuts "freely," 
thereby reducing frictional heat. The proper 
relation between feeds, speeds and cuts should 
be determined to get the best results. Smooth 
surfaces are essential; tool marks must be 
avoided. Keyway bottoms and all shoulders 
at changes in diameter should be generously 
filleted.

ELASTUF TYPE A 

ALLOY MACHINERY STEEL 
ANNEALED 

ANALYSIS: All stock sizes are .45/.5S Carbon. Unless 
otherwise specified, all sizes will be furnished in this 
carbon. In other respects analysis is the same as the 
heat treated stock. 

GENERAL PURPOSES: For parts requiring physical 
properties beyond the range of machinability. In such 
cases ELASTUF TYPE A, Annealed, should be used, 
and hardened after machining. Recommended for 
clutches, cams, ratchets, clash gears, extra heavy duty 
bolts, forming dies, etc. 

CHARACTERISTICS: It is possible to obtain hardness 
on ELASTUF TYPE A comparable with tool steel, 
but with considerably greater toughness. Note pre- 
viously quoted figures on Impact Strength. 
The use of ELASTUF TYPE A, Annealed, is indicated 
in preference to tool steel or carburized steel for many 
machine parts (not for cutting tools). 

HEAT TREATMENT: Forge at 2200/2300° F. 
Anneal at 1450/1500° F. 
Harden at 1500/1600° F — Oil Quench. 
Draw to requirements. 300/350° F. will relieve quench 
strains and give maximum Torsional Impact Toughness. 

DISTORTION: Due to carefully determined carbon and 
manganese content, ELASTUF TYPE A is remarkably 
free from distortion in hardening. This makes it useful 
for parts that are intricate, such as curved cams, moulds, 
mandrels, etc. 

PHYSICAL PROPERTIES: (1 " Rd. Oil Quenched from 
1550° F.)

TROJAN TOOL STEEL 

A quality steel of moderate price 
Characteristics: Hardens well and is especially 
strong and tough. Welds and forges readily. 

Uses: No. 8 Temper .7S/.85 Carbon: Recom- 
mended for pick points, hand chisels, black- 
smith, mine and quarry tools, fire tools and 
street tools (hand and pneumatic). 
No. 9]/ 2 Temper .90/1.00 Carbon: Recom- 
mended for brake and forming dies, forging 
dies, and for a large variety of tools not re- 
quiring the quality of our higher grade steels. 

Heat Treatment: Anneal at 1450 to 1500° F. 
(light cherry); harden at 1400 to 1500° F. 
(full cherry to light cherry), depending on 
size, shape and temper (carbon content). 
Water quench and temper at 350° F. to relieve 
strains. A higher draw will increase toughness 
and decrease hardness.

■ ^S^^9^ THIS ST£U HAS BEIN 

Hjflfc Dl/CIN/PECTED 



The Carpenter Steel Company has developed processes 
I of manufacture," testing and inspection which have resulted 
in tool steels of surpassing quality. 

The expression "Tough Timbre Tool Steel" was at 

first thought to be an indefinable quality that could only 

be obtained in the laboratory. Shop results, however, 

I have been so excellent that now the tool steel user has at 

his disposal steels of quality heretofore unknown. 

"Tough Timbre" in water-hardening carbon tool steel 
means that it is difficult to crack in hardening, difficult to 

I check in grinding, and difficult to ruin in service. Further- 
more, it means that every bar will harden alike, show the 
same penetration of hardness, the same expansion or 

■ contraction in hardening and must have the same ability 
to perform in service. 

■ The Acid Etch is the most dependable method of secur- 
ing tool steel that is free from center sponginess, slag in- 
clusions and other imperfections that so frequently result 

| in broken tools, after all the labor has been spent. 

Carpenter Tough Timbre Tool Steel is warranted 
■clean, sound and uniform, having been subjected to the 
acid etch inspection. All bars carry the DIOK label, 
meaning "Disc Inspected O.K." 

Due to the continued brilliant research work done by 

Carpenter, it is now possible to measure the toughness 
>f hardened tool steel. This is done on what is known as 

the Torsion Impact machine, developed by Carpenter. It 

has proven of great value to the tool steel user. It has indi- 
ated proper methods of heat treatment and has enabled 

the heat treater to improve the service life of tools; it has 
ihown, for instance, the effect of different hardening tem- 
peratures, different drawing temperatures, different 

furnace atmospheres, etc., on the toughness of hardened 
|tool steel. There is a temperature for drawing that gives 

the maximum torsional impact strength and this figure is a 

guide to the service life of a tool. 

The Carpenter Steel Company is producing tool steels 
of unusually high quality, which means that the user 
|can confidently trust any job, no matter how difficult, to 
a Carpenter Tool Steel. 

| These steels are stocked, serviced and sold by us, and we 
offer our complete facilities to the tool steel user.

(Water-Hardening) ^^ 

TOOL STEEL 



CHARACTERISTICS: A general purpose water hard- 
ening tool steel manufactured with special attention too^ 
quality and uniform hardening properties. Every bar^*" 
bears the DIOK label — meaning "Disc Inspection 
O.K." It is also Tough Timbre and Hardenability§| 
Tested. 

USES: Blanking, punching, shearing and forming^*" 
dies, shear blades, broaches, counter bores, coping 
knives, jewelers' dies, steel stamps, milling cutters,| 
punches, dies, taps, reamers, etc. 

HEAT TREATMENT: The extensive research work* 
done on water-hardening tool steel by The Carpenter 

Steel Company has resulted in the production of steels|^p 
possessing remarkable response to heat treatment. This 
is manifest in the lessened tendency to crack or bean 
brittle in the hardened condition. These characteristics^^ 
result in what is acclaimed * 'Tough Timbre Tool Steel. "^^ 
To Anneal: At approximately 1400° F., cool slowly. If 
To Harden: Heat slowly and uniformly in a neutral 
or slightly oxidizing atmosphere to 1450° F. and quench^ 
in 5% to 10% salt brine. Brine is much better than 
fresh water for all water-hardening tool steels. For^^j 
maximum combination of hardness and toughness,^^ 
draw at 350° to 375° F.

various temperatures:

CARPENTER MATCHED 
TOOL STEELS 

Carpenter Matched Tool Steels are a group of nine tool 
steels, represented by the nine diamonds shown below. 



THE OIL-HARDENING THE WATER-HARDENING 
MATCHED SET MATCHED SET 



THE RED-HARD 
MATCH EO SET 




ACCURACY AND SAFETY 



These nine steels will solve practically any tool problem 
that can come up in the tool room. 

They are called "Matched Tool Steels" because each one 
picks up its job where the other leaves off. They dove- tail 
so closely together that you can know in advance what the 
results will be as you switch from one steel to another. 

The key steel is the one in the center — No. 11 Special. 
This is a 1.10% carbon, water-hardening tool steel. 

HOW THE DIAGRAM IS USED 

When you have a tool to make, you ask yourself: 
"Should I make this tool from No. 11 Special?* 7 Many 
times the answer will be: "Yes." In that case, you of course 
go no further. But suppose the answer is: "No," what 
then? You then ask the second question: "Why not?" 

There can be only four answers to the second question, 
and on the Matched Diagram each answer is assigned to 
one point of the compass — north, south, east and west. 
Here are the four answers. 

Answer No. 1: "Because greater wear resistance is 
needed." 

This is a perfectly good answer — perhaps the tool in 
question could be made of No. 11 Special but it must run 
day after day and you want to get maximum wear re- 
sistance so that the production per dressing will be as 
great as possible. 

154 



HORACE T. POTTS CO. 



I On the Matched Diagram you always get more wear re- 
sistance by travelling north. Immediately north of 
WggfVo. 11 Special is K-W. K-W is a water-hardening 
-alloy tool steel very much like No. 11 Special excepting 
— , pjthat it will wear from four to ten times as long. So, in 
^^bhis case, you make the tool of K-W. 

mmm Answer No. 2: "Because greater toughness is required." 
^"^ Some tools like shear blades, chisels, boiler punches, 
spring collets, etc., require more toughness than you get 
■a^n a high carbon steel like No. 11 Special. 

On the Matched Diagram you always travel south to 

3get greater toughness. Directly south of No. 11 Special 

you come to Solar. This is another water-hardening alloy 

^■steel, much like No. 11 Special excepting that it is many 

"times tougher. Therefore, you make these tough tools of 

lar. 

NOTE: When you travel north to secure 
greater wear resistance, you are going away 
from toughness, which is in the south. 
Hence, K-W is not as tough as No. 11 
Special. 

Also, when you travel south for greater 
toughness, you are travelling away from 
wear resistance, which is up north. Hence, 
Solar is not as wear resisting as No. 11 
Special. 

Answer No. 3: "Because greater hardening accuracy and 

fety are needed than can be expected of a water-hard- 
ening tool steel." 

I Many tools cannot be ground after hardening and must 
accurately hold their shape. Also, some tools are so 
Intricate in their shape that they might crack if quenched 
in water. 

■ On the Matched Diagram, hardening accuracy and 

safety are found in the west. So you proceed west from 

11 Special and come to Stentor. Stentor is an oil- 

ardening alloy tool steel that is used for just about the 
same line of tools as No. 11 Special — excepting that it is 

afer to harden and holds its size and shape more accurately 
during the quench. 

Answer No. 4: "The tool gets hot in service and No. 11 

Ipecial would lose its temper." 

Many tools such as high speed cutting tools, and tools 
Tor hot forging, hot extruding, hot molding, etc., reach a 
degree of temperature in service that will soften a plain 
larbon tool steel. 

On the Matched Diagram, red hardness is found in the 
|ast. Directly east from No. 11 Special is D. Y. O. steel. 
This is a high tungsten alloy steel that is scarcely affected 
[it all by temperatures as high as 1200° F. This is there- 
fore the direction to go in response to Answer No. 4.

HORACE T. POTTS CO. 



Thus, the four points of the compass take care of the£ 
only four possible answers to the question "Why not use 
No. 11 Special?" m m 

There are literally hundreds of tools that can be and 
should be made from No. 11 Special. This steel forms^ 
the starting point for all of your thinking. The MatchedH 
Diagram provides four positive directions in which you 
can go to secure additional properties beyond thoseHj 
possessed by No. 11 Special. 



„ r Greater Accuracy 
and Safety 




e 



Red 



HardncM 



-E 



Sometimes the tool maker wants two things at once 
For example, he might want greater wear resistance ancC 
also greater hardening accuracy. If so, he travels north 
for wear resistance and west for accuracy and comes t(JP 
Hampden. 

Similarly, he might want greater toughness and harden* 
ing accuracy at the same time in which case he would travel 
south and then west and come to R. D. S. -^ 

E 

If he wanted maximum hardness and wear resistance in a 
red hard steel, he would travel east and north and arrive—, 
at Star-Zenith High Speed Steel. • 

To get red hardness with maximum toughness, he woulc^ 
travel east and south to use Excelo. Hi 

Due to the matched relationship between these nin?-- 
steels, a tool maker who is familiar with any one of thenfc 
can move into the adjoining diamonds and forecast his 
results with considerable accuracy. Thus, he gradual!^ 
becomes acquainted with the entire set. 

THE KEY STEEL E 

No. 11 Special is the most important member of the 
entire set. It will do more jobs than any other steel, it iS 
the easiest steel to machine, easy to harden and will average 
to make less expensive tools than the higher alloyed 
materials which surround it. Therefore, a tool maker 
should never travel away from this steel unless it i^ 
necessary. • 

156 

I 



HORACE T. POTTS CO. 



No. 11 Special is a Tough Timbre tool steel. Timbre 
is the property of high carbon, water-hardening tool steel 
that controls the grain size and penetration of hardness. 
It has nothing to do with the chemical analysis of the 
steel. 

The Tough Timbre kind will withstand accidental over- 
heat in hardening without damage; it is much less likely 
to crack in hardening; and it makes tougher and stronger 
tools without sacrifice of hardness. For further details, 
ask for our book " Tough Carbon Tool Steel," which 
describes Timbre and how it affects tools made from 
carbon tool steel. 

If you have been using some high carbon water-harden- 
ing tool steel other than No. 11 Special, you cannot 

I appreciate the. many tools that can be made from this 

' Tough Timbre steel. No. 11 Special is as different from 
the old fashioned water-hardening tool steels as a modern 

| tire is different from the old fashioned tires. We used to 
brag about the tires that gave us 4,000 miles of service — - 

| but at that time we had not been spoiled by anything 

better. Today no one would tolerate a low mileage tire. 

Just so, many tool makers do not realize what can be done 

I with a Tough Timbre water-hardening tool steel because 
they are still using the old kind. Quite a few of these men 

| have practically abandoned water-hardening tool steels in 
favor of alloy steels — just because they found the old 

- fashioned water-hardening tool steels so undependable. 
■ As a result of this "flight from carbon tool steel," they now 

say that they are not having any trouble with their water- 
I hardening tool steel—but really this is because they give it 

only the most unimportant jobs to do. 
I There is now a definite movement back to water-hard- 
ening tool steels because tool makers have found in Tough 
Timbre steel a means for safely returning to the easy 
I machining, the glass hard surface and the clean cutting 
efficiency of a water-hardening steel. 

If you were using the old fashioned "brittle timbre" 
carbon tool steel, your Matched Diagram would look like 

- this.

" Brittle timbre" steel covers so little territory that it 
can be used for only a small number of tools and the tool 
maker is very frequently called upon to reach out for some 
alloy steel. Due to its limitations, brittle timbre is not 
matched with the steels that surround it — there are gaps 
between. For example, the brittleness of brittle timbre 
steel might drive a tool maker south toward Solar. After 
the tool was made of Solar it might lack sufficient wear 
resistance for its purpose. What would he do then? 

It is evident that this particular tool falls in the open 
space between brittle timbre steel and Sola r. The only re- 
course would be to hunt outside the Matched Diagram 
for some other steel to fill the gap. This defeats the very 
purpose of the Diagram which is to use the smallest pos- 
sible number of steels and have them so closely matched 
that you can go from one to the other without any gaps. 
To use the Carpenter Diagram with other steels substi- 
tuted here and there is dangerous business. Every time 
you do this you are almost sure to break up your Matched 
Set and get awkward spaces that will have to be filled 
with some other unmatched steels. Ultimately you get 
right back to a big assortment of steels — each of which is 
good for only a few jobs and you have lost the advantages 
of the Matched Set principle. 




ADVANTAGES OF USING MATCHED 
TOOL STEELS 

The advantages of using Matched Tool Steels are these : 

1. It enables the tool maker to select the proper type 
of tool steel for each job. 

2. If a certain grade of steel fails to*meet the require- 
ments of a tool, the tool maker knows exactly which 
steel to pick to correct the trouble. 

3. The group totals only nine steels — and many tool 
makers do not even need to use all of these. This 
makes for simplification in the tool room. 

4. Tool Steel inventories are less because there are a 
smaller number of steels to use. 

5. Heat treating problems are minimized by using only i 
a few tool steels. 

6. The performance of finished tools will be increased j 
by proper selection of tool steels and simplified heat 
treatment. 

7. Best of all — the tool maker does not have to depend 
to a large extent upon outside advice in the choice j 
of his tool steels or the solution of his steel problems. 
He does it himself and knows exactly what he is t 
doing and why he is doing it.

SIMPLIFIED HEAT TREATMENT 

The heat treatment of Carpenter Matched Tool Steels 
has been simplified beyond anything previously known. 

A tool must be hard enough to resist wear, and tough 
enough to avoid breaking. We have never had much 
trouble measuring the hardness of a tool steel, but it has 
been practically impossible to measure its toughness. 
For this reason, it has always been necessary to do a lot 
of cutting-and- trying in order to find the heat treatment 
that would give the best combination of hardness and 
toughness. 

About five years ago there was developed in Carpenter's 

Research Lab- 
oratory a test- 
ing machine 
that would 
measure the 
toughness of 
hardened tool 
steel. This ma- 
chine is known 
as the "Car- 
penter Torsion 
Impact Testing 
Machine" and is now manufactured and sold as a standard 
testing machine by the Baldwin-Southwark Corporation, 
Philadelphia, Pennsylvania. 

A test piece is machined 
to the shape shown at the 
right. It is heat treated, 
and then broken in the test- 




The first Torsion Impact Machine. 



The Test Specimen. 



ing machine by a torsional impact blow. The force re- 
quired to break it is measured in "foot-pounds." One 
foot-pound is the blow struck by a one pound weight 
falling one foot. Ten foot-pounds would be the energy of a 
ten pound weight falling one foot (or a one pound weight 
falling ten feet). 

Now suppose we had a plain high carbon, water-harden- 
ing tool steel and wanted to know what drawing tempera- 
ture should be used to secure the best combination of 
hardness and toughness. We would machine a lot of 
torsion impact test pieces, harden them all exactly the same 
way and then draw them all at different temperatures. 
When we measure their hardness and toughness, we get the 
figures tabulated on page 160. 

Observe that the toughness as quenched is only 26 foot- 
pounds, but it increases rapidly to over 120 foot-pounds 
as the drawing temperature is raised to 350°/375° F. 
Then, strange as it seems, the toughness falls off rapidly 
again at higher drawing temperatures until it is less than 
half the "peak" value. Upon drawing above 5 00° F. 
the values increase again.

Hundreds of these toughness curves have been made and 

every hard tool steel that has been tested shows either one 

or two of these toughness * 'peaks." Practical experience 

over a period of about three years in commercial tool 

rooms proves that in a vast majority of cases, the best 

results are secured from tools drawn at this toughness 

"peak."

HORACE T. POTTS CO. 



| There seem to be just enough exceptions "to prove the 
rule." Every now and then we get reports of tools that 
appear to give better service when drawn higher than the 
"oughness "peak." The reason for these exceptions is not 
known, but it is doubtless due to something unusual in 
|he size, or shape, or service of the tool. 

Throughout this manual, we will give the torsional im- 

ict curve for each tool steel in the Water-Hardening and 

il-Hardening Matched Sets. In the tables of drawing 

-temperature, the temperature corresponding to the tough- 

'less "peak" is emphasized. In the Red-Hard Matched Set, 

torsional impact curves are not given because these steels 
|>perate at elevated temperatures where toughness figures 

are not yet available. In drawing these three Red-Hard 
giteels, we usually aim for the secondary hardness peaks, 

where maximum red-hardness is secured. 
m If you will always start out using these preferred tem- 
Pperatures, you will eliminate a tremendous amount of 

cutting-and-trying, and will greatly improve the average 
performance of your tools. 

I NAMING THE MATCHED 
STEELS 

I The Carpenter Steel Company has always used brand 
names for their tool steels. These names are well known 
|:o our customers and have acquired a definite meaning in 
"thousands of plants. 

■ To assist in remembering and placing these nine steels on 
che Matched Diagram we have given to each one a new 
subsidiary name. These new names are shown in the dia- 
gram below along with the regular brand names.

For example, Hampden Steel is the wear resisting 
member of the Oil-Hardening Matched Set. We, there- 
fore, name it * 'OIL- WEAR," 

Stentor, which is the intermediate steel in the Oil- 
Hardening Set, will be called "OIL-HARD." - 

R. D. S. is the tough member of the Oil-Hardening 
Matched Set and will therefore be called "OIL-TOUGH." ■ 

In the Water-Hardening Matched Set, K-W is called 
"WATER- WEAR." No. 11 Special is called "WATER-HARD.'B 
Solar is called "WATER-TOUGH." 

In the Red-Hard Matched Set, Star-Zenith is "REd| 
WEAR"; D. Y. O. is "RED-HARD" ; Excelo is "RED-TOUGH." 

These are new trade-marked names of the Carpente^ 
Matched Tool Steels. In ordering any of these steels or in 
writing about them, our customers can use either of theg 
two names and no confusion will result either at the milr 
or in our Branch Warehouses. "Solar" and "WATER 
TOUGH" are simply two different names for the sam< 
thing — just like "Napoleon" and "Bonaparte" are two 
names for the same individual. 



LABELS E 

The label attached to each bar of Matched Tool Stee^^ 
when it is shipped is reproduced in color on the following^ 
pages as each Matched Tool Steel is individually described. 

You will note that the labels for all of the oil-hardening^ 

steels are blue, the water-hardening steels are green, and 

the red-hard steels are red — duplicating the colors thatjj 
appear in the Matched Diagram. 

The black bar on the label tells you instantly whether itflE 
is the top steel, the middle steel or the bottom steel of the 
set. £j 

Each label also gives the brand name and the Matched 
Diagram name of the steel. 

You can identify a bar of Matched Tool Steel as far a s _ 
you can see the label and this will help to avoid any possible! 
errors in misapplying the various grades of steel.

Type Analysis: Carbon 1.10%

Alloys None 

PROPERTIES 

I DESCRIPTION; No. 11 Special is a high carbon, 
water-hardening tool steel. It is guaranteed to be Tough 

(Timbre, with a medium hardness penetration. 
In sections larger than about J^ , it 

■hardens with a dense, fine grained case — 
and a tough, coarser grained core. It 
owes its hardness and wear resistance to 

Pthe case, and its toughness to the softer 
core. 

No. 11 Special is 100% acid disc inspected in the billets 
during manufacture to insure clean sound steel in every bar. 
DEFORMATION IN HARDENING: Being a water- 
hardening steel, No. 11 Special will not hold its exact size 
or shape during hardening. However, if we are to judge 
from the number of tool makers who have switched from 
oil-hardening tool steel back to No. 11 Special, it must be 
Ifar above the average in this respect. 

DECARBURIZATION: No. 11 Special has no un- 
usual tendency to decarburize when heated for hardening. 
The furnace atmosphere should be neutral or slightly 
oxidizing. 

MACHINABILITY: No. 11 Special is the easiest of 
all tool steels to machine. The absence of special alloys — 
and good annealing are responsible for this. 

USES OF No. 11 SPECIAL: All tools should be made 
[of No. 11 Special unless there is some good reason for 
making them from some special alloy steel. This is the 
first rule of the Matched Diagram. Typical uses include: 
Drills Threading dies Cutters 

Taps Blanking dies Hobs 

Reamers Striking dies Knurls 

Punches Forming dies Jig bushings 

Arbors Bending dies Jigs and fixtures 

Stamps Button dies Jig feet 

Bushings Coining dies Dowel pins 

Knurls Ring gauges Adaptors 

Mandrels Plug gauges Locating studs

WHEN TO SWITCH FROM No. 11 SPECIAL: | 

If you want greater wear resistance (at some sacrifice of 
toughness) use K-W (WATER- WEAR). 

If you want greater toughness (at some sacrifice of wear 
resistance) use Solar (WATER-TOUGH). 1 

If you want great hardening accuracy or safety, use 
Stentor (OIL-HARD). This steel is used for the same| 
type of work as No. 11 Special. ' 

If you want red-hardness for hot forging tools, switch tc| 
D. Y. O. (RED-HARD). For red-hardness in a metal' 
cutting tool, switch to Star-Zenith High Speed Steel 
(RED-WEAR) . 



THE HEAT TREATMENT OF 
No. 11 SPECIAL 

To Forge: Heat slowly and uniformly to a maximum 



I 



I 



temperature of 1950° F., and forge. Cool in air in a dry, 



place 



I 



To Normalize: Forgings are normalized by heating to 
1650° F. and cooling in air. 

To Anneal : Pack in a suitable container with clean cast 
iron borings, heat uniformly to 13 50°/ 13 75° F., and cool| 
slowly in the furnace. Brinell hardness 160 to 190. 

To Harden : Heat slowly and uniformly in a neutral or 
slightly oxidizing atmosphere to 1450° F. and quench inl 
5% to 10% salt brine. Hardening temperatures under 
1440° F. are not recommended for this steel. 1 

Brine is much better than fresh water for quenching all 
of the water-hardening steels of the Matched Set. 

Coining dies, striking dies, heading dies, etc., which are" 1 
under heavy pressure, can be hardened at higher tempera- 
tures such as 1500°, 1550° or even 1600° F. to increase the| 
penetration of hardness to prevent sinking. 

Hollow impressions on dies should be flushed in quench-j 
ing. Fresh water is satisfactory as a flush. 

In sizes equivalent to about 3/16" round, or smaller, 
No. 11 Special will become file hard when quenched inl 
oil from about 1500° F. This practice is recommended on 
very small parts to reduce warping, deformation and! 
possible cracking. 

To Draw: The real purpose of drawing is to remove- 
internal strains and increase toughness. A procedure™ 
should therefore be adopted which will give the best 
toughness with the least possible sacrifice of hardness. 

The curve given on page 165 shows how various drawing 
temperatures affect the torsional impact toughness ofg 
No. 11 Special and the table which follows gives the' 
corresponding Rockwell and Scleroscope hardness values-

No. 11 SPECIAL 

(WATER-HARD) 

Effect of Hardening Temperature and 
Drawing Time: 

While most No. 11 Special tools should be hardened | 
from 1450° F., certain types of cold forming tools require 
higher hardening temperatures. Further, exceptionally 
large or intricate tools should frequently be soaked at the I 
drawing temperature longer than one hour. To find the 
best drawing temperature for each hardening temperature | 
and each drawing time, refer to the following table.

First, find in the left hand column the hardening tem- 
perature used; then decide how long the tool should be, 
soaked at the drawing heat and use the drawing tem- 
perature given in the table. 

For example, if you harden a tool at 1500° F. and I 
decide to draw it four hours, draw it at 350° F. If you 
quench at 1550° F. and are going to draw 1 hour, use 400° F. 
If you quench at 1450° F. and want to draw 24 hours, use 
a temperature of 275° F. 

Small tools of very simple shape are sometimes drawn 
less than one hour. A tool drawn for only 15 minutes i 
should receive 25° more drawing heaf than is recom- ' 
mended for a one hour draw. 

Small tools hardened in oil should be drawn the same as * 
though they had been quenched from a corresponding 
temperature into water. 

You seldom need to bother trying any other drawing 
temperature than the one you pick from the above table 

We do not recommend drawing No. 11 Special sjfter 
than about C-62 Rockwell. If this is not tough enough, j 
you have the wrong steel and should switch to Solar 
(WATER-TOUGH). This, of course, does not apply to. 
shanks and other parts of tools remote from the "business I 
end" which might need to be softened for special reasons.

SOLAR 

(WATER-TOUGH) 




Hi 



Type Analysis: Carbon 50% I 

Manganese 40% 

Silicon 1.00% | 

Molybdenum 50% 

PROPERTIES | 

DESCRIPTION: Solar is a water-hardening alloy tool 
steel of extreme toughness. It hardens to about C-62| 
Rockwell, and when drawn back to about C-59 Rockwell, 
it is the strongest and toughest tool steel known. 

A tensile test on Solar, properly treated, will show: 

Breaking strength 323,000 pounds per sq. in. I 

Elongation in 2" 4.5% 

Even with this great hardness and strength, Solar ij 
ductile enough to stretch more than 4% before breaking. 
At C-59 Rockwell, Solar will bend before it will break! 

When hardened in me- 
dium and large sized 
pieces, Solar acquires a 
hard case and a tough 
core. For example, in the 
1}^" round piece shown, 
there is a fine grained case 
about 3/16" to \i" deep 
showing C-61 /63 Rock- 
well hardness; and a 
tough, coarser grained 
core showing about 
C-40/45 Rockwell. Sizes 
under %" round will harden clear through. ^== 

DEFORMATION IN HARDENING: Since Solar 
hardens deeper than No. 11 Special (WATER-HARD), ifM 
tends to expand more in hardening. Solar will expands 
in larger sizes where the straight carbon steel would- 
shrink. Also, rectangular blocks of Solar will tend td 
harden with concave faces. That is, the flat surfaces 
will become slightly hollow, whereas No, 11 Specia^ 
would bulge under similar conditions. Solar is not rec- 
ommended for tools that must hold size and shape accu| 
rately in hardening. This is the field for R. D. S. (OIL* 
TOUGH).

DECARBURIZATION: Because of its high content of 

silicon and molybdenum, Solar is more likely to decar- 

ourize when heated than any other steel in the Matched Set. 

m This is virtually the only bad habit Solar has — and 
even it can be avoided by proper heating and furnace con- 
trol (see hardening instructions). If Solar tools are gen- 

lerously ground after hardening, decarburization does not 
matter. 

| MACHINABILITY: Being an alloy steel, Solar does 
not machine as readily as No. 11 Special. It is not as 

■difficult to machine as High Speed Steel, but might be 
classed as intermediate between these two. 

• USES OF SOLAR; The rule of the Matched Diagram 
"s: — When No. 11 Special (WATER-HARD) is not tough 

enough for a job, travel south and use Solar (WATER- 
ProuGH). As a general rule, you do not draw No. 11 

Special below C-62 Rockwell — if this is not tough enough, 
»jse Solar. 

Solar hardens to about C-61 to C-63 Rockwell and after 

•drawing to C-60, it is very much tougher than No. 11 

Special (WATER-HARD) would be at this same hardness. 

m In almost every tool room and shop, there are a vast 
number of tools or parts that must, above all else, be tough. 
Along with this toughness we want all the hardness and 

Pwear resistance we can get, but they must not break. 
Here are just a few, as reminders— you can fill in the list 

■almost without limit. 

Long slender punches Heavy duty forming tools 

■Punches with fragile projections Heavy duty bending tools 

Heavy duty perforating punches Heavy duty coining dies 

Knock-out pins Shear blades 

iFingers Spring collets 

Clutch pins Feed fingers 

1 Stops Special knurls 

Indexing pins Stamps 

I Screw extractors Circular shear blades 

If these tools were made of straight carbon tool steel, 
you would draw them back to a "blue"— and often "blue" 
■ isn't half far enough. Solar fits into this field like a key 
into its lock. 

Here is another group frequently referred to as "batter- 
ing tools":

SOLAR I 

(WATER-TOUGH) 

All of these tools demand a combination of hardness and^ 
toughness that can be squeezed out of carbon tool steel 
only by lowering the percentage of carbon and draw in M 
back entirely too far. There is not a job in this list that 
Solar has not done — and done well. For most of them* 
it is by far the best steel we know of— regardless of price.™ 

WHEN TO SWITCH FROM SOLAR: . 

1. If you want greater hardness and wear resistance 
than Solar can deliver, use No. 11 Special* 
(WATER-HARD). I 

NOTE: Do not make this shift until you are sure 
your trouble is not due to surface decarburizationjl 
Grind or file below the surface and see whether the 
hardness increases. If it does — try to do a better! 
job of hardening before trying No. 11 Special. 

2. If Solar changes size or warps too much in harden-- 
ing— or if the shape is so intricate that you do not! 
dare to quench it in water — use R. D. S. (OIL- 
TOUGH). This steel is used for the same generall 
purpose as Solar but it is oil-hardening and non- 
deforming. 

3. If the tools get hotter than 300° F., in service 
go east and select Excelo (RED-TOUGH). 



I 



THE HEAT TREATMENT OF SOLAR 

To Forge: Forge from a temperature not over 2100° F.| 
Heat rapidly and avoid unnecessary soaking in order to 
minimize surface decarburization. Cool the forgings in 
air in a dry place. 

To Normalize: Forgings are normalized by heating to 
1650° F. and cooling in air. 

To Anneal : Pack in a suitable container with clean cast ! 
iron borings. Heat uniformly to 1350° to 1400° F., and- 
cool slowly in the furnace. Brinell hardness will average! 
190 to 220. 

To Harden: Heat uniformly to 1550°_F. and quench in| 
5% to 10% salt brine. Leave the tools in the brine until 
cold enough to handle. 

Small parts may be heated to 1600° F. and quenched 
in oil. 

To prevent surface decarburization (or bark), heat in a I 
lead pot when practicable — or if a furnace is used — adjust 
the valves so there is a flame floating in the furnace, theni 
add a shade of air so the flame just disappears. This 
gives you a slightly oxidizing atmosphere which will pro- - 
duce the greatest skin hardness. Heat the steel quickly and ■ 
soak it only long enough to heat the piece clear through. 
A smoky furnace atmosphere will decarburize Solar. 

To Draw: The effect of drawing upon the torsional ! 
impact toughness and hardness of Solar is as follows'

For practically all water (or brine) quenched tools, we 
recommend a drawing temperature of 275° to 300° F. for 
one hour — or longer, according to size. Shanks of pneu- 
matic chisels are drawn at 900° F. 

When Solar tools are oil quenched from 1600° F., they 
frequently need not be drawn at all and will then show 
C-59/61 Rockwell. If the shape is intricate, draw at 
200° to 250° F., to relieve the hardening strains. 

Do not draw Solar to color, because a straw color begins 
to appear above 400° F. — which is too hot for most tools.

K-W 

(WATER-WEAR) 





■Type Analysis: Carbon 1.30% 

Manganese 30% 

Silicon 45% 

I Tungsten 3.50% 

B _ PROPERTIES 

DESCRIPTION: K-W is a water- 

—hardening tool steel that will resist $£ 
^vear and abrasion from four to ten 

times longer than plain carbon tool 
^teel. When hardened, it acquires a 

peculiar slippery-hard surface which 

Ks so difficult to scratch that even an „ J, 5 !? F * 
K-W Fracture 
ordinary emery wheel can scarcely cut 

it. Special wheels are used for grind- ^^^ 

Bng K- W tools as described on page 1 79. ^ppiWh^ 

Because of the "soapy" nature of the K$\ ^^ 
■hardened surface, K-W tools do not ■ 

gall or pick up as quickly as other ^L ^^m 

—tools. ^^M^r 

K-W is a surface hardening steel and 1550° F. 

hardens with a somewhat thinner case K ~ Disc ed 
■:han No. 11 Special* The hard case 

is backed up with a coarser grained, tougher core having a 
■Rockwell hardness of about C-45/50. K-W billets are 

100% acid disc inspected to insure clean sound metal in 
^the finished bars. 
' DEFORMATION IN HARDENING: Being a shallow 

hardening, water quenched steel, K-W tends to shrink in 
■hardening. This is a useful property in draw dies which 

can frequently be shrunk enough in rehardening to take 
■up the wear, thus allowing them to be re-used for the same 

size. 
m K-W is not recommended for tools that must hold size 

iand shape accurately in hardening. For such tools, use 

Hampden (OIL-WEAR). 

I DECARBURIZATION: Tungsten increases the ten- 
dency toward surface decarburization in hardening. Also, 
J: he higher hardening temperature of K-W (1525° to 

1600° F.) helps this tendency along. Generous grinding 
^allowances should be made where possible, and if not — 
'pay particular attention to the hardening instructions so 

that decarburization may be avoided.

K-W t 

(WATER-WEAR) 

MACHINABIUTY: K-W machines almost as well asftS 
No. 11 Special, It averages to be a little bit harder. 

USES OF K-W : The rule of the Matched Diagram is— ^ 
use K-W for all water- hardening tool steel jobs where 
you want more wear resistance and greater productions^ 
than No, 11 Special (WATER-HARD) will deliver. ^B 
Therefore, K-W has been successfully used for a wide 
variety of tools. The following is a typical list selected (| 
from letters that our customers have written us about the 
uses of this steel: m 

Guide strips 

Forming dies 

Forming rolls 

Cam rollers 

Arbors 



Plug gauges 

Push broaches 

Burnishing plugs 

Sizing plugs 

Burnishing tools 

Tube drawing dies Forming punches 

Wire drawing dies Die collars 

Draw dies for Nibbling punches 

stainless steel Brass cutting 
Extruding dies tools 

(cold) Special stamps 



Notching punches 
Stone planer tools wd/M 
Reamers "'* 

Turning tools 

(cast iron) | 

Combination dies 
Sectional blanking Mm 

dies 
Piercing punches ^_^ 
Ball header dies 



WHEN TO SWITCH FROM K-W: * 

If you want greater toughness, use No. 11 Special 
(WATER-HARD). 

If you want greater hardening accuracy or safety, use 
Hampden (OIL- WEAR). This steel is used for the samel 
wear resisting jobs as K-W, 

If service temperature gets above 300° F. and softens the- 
K-W tools, use Star-Zenith High Speed Steel (RED-' 
WEAR). This steel likewise possesses great wear resist- 
ance and will function at temperatures up* to 1100° F. 

If the shallow hardened case of K-W limits its use on 
heavy coining and compression tools, use Hampden (OIL ■ 
WEAR) which hardens very deep. 

If hardness or wear resistance seem lacking, the trouble 
is probably surface decarburization or some- other harden- | 
ing difficulty. There is no more wear resisting steel than 
K-W. I 

THE HEAT TREATMENT OF K-W 

To Forge: Forge from a temperature not over 1900° F.| 
and allow the forgings to cool in air in a dry place. 

To Normalize: Forgings are normalized by heating to- 
1675° F. and cooling in air. I 

To Anneal: Pack in a suitable container with clean cast 
iron borings, heat uniformly to 1440° to 1460° F. and cool| 
slowly in the furnace. Average Brineli 200 to 230. 

To Harden: Heat uniformly to 1525° to 1600° F. (accord-j 
ing to size and hardness penetration desired) and quench 
in 5% to 10% salt brine. i

s To avoid surface decarburization, adjust the burners so 
that there is a flame floating in the furnace, then add a 

*H shade of air so that the flame just disappears. This will 
produce a slightly oxidizing atmosphere which will pro- 

Mkduce maximum sur- 
face hardness. If a 

t^K-W tool appears to 
have failed to harden 

^ properly, explore it 
for decarburized skin 

a_ before attempting to 
reharden it. Re- 

^^ hardening will only 

'^ serve to make a *de- 

^carburized surface 

^^ worse. 

*m To avoid soft spots 
(due to the shallow 

4» hardening nature of 
this steel) never use 

4| fresh water for 
quenching excepting 

4^ in a flush. Always 
use 5% to 10% salt 

^b rine in a still 
quenching tank. Use 

^•flushing fixtures 
for quenching K-W 

^m tools that have hol- 
low impressions — as 

p^suggested by the 
sketches.

The above data shows that the best combination of hard- V™ 
ness and toughness is secured by drawing between 350° 
and 375° F. ^_ 

K-W should seldom be drawn hotter than 400°/425° F.B^ 
If greater toughness is needed, switch to No. 11 Special 
(WATER-HARD). g^— 

Draw rings that are hardened in the hole only are*^ 
frequently used without drawing at all. 

To Grind: Because of its extreme wear resistance, K-W I 
is difficult to grind with the usual grinding wheels. The

STENTOR 

(OIL-HARD) 



STENTOR 

OIL -HARD 
MATCHED TOOL STEEL 



Type Analysis: Carbon 90% 

Manganese 1.60% 

Silicon 25% 

PROPERTIES 

DESCRIPTION: Stentor is an oil-hardening, non- 
deforming tool steel. It possesses maximum safety from 
hardening cracks when quenched in intricate sections and 
will harden with a minimum of size change and warpage. 

Stentor is made from billets that are 100% acid disc in- 
spected which insures clean sound metal in the finished 
bars. 

DEFORMATION IN HARDENING: Oil-hardening 
steels hold size best only when quenched from the proper 
hardening temperature. If overheated they tend to 
expand; and if underheated they tend to shrink.

When properly hardened, Stentor will expand slightly — 
but upon being drawn, it returns very closely to its original 
size. The chart shows the average size change in Sten tor 
per inch of length. That is, a piece 1" long will expand 
approximately .001" when hardened, but upon being 
drawn between 300° and 400° F., it will return within 
about .0004" of its original size. 

Because Stentor is free from alloys like tungsten, chro- 
mium, etc., it hardens at a very low temperature (1400° to 
1440° F.) f which holds warping down to an absolute 
minimum.

STENTOR 

| (OIL-HARD) 

DECARBURIZATION: Stentor is no more subject to 
I surface decarburization than No. 11 Special (WATER- 
HARD). This is very important because Stentor holds 
■ F.Ize so accurately that many people do not grind their tools 
after hardening. The freedom of Stentor from soft skin 
is so unusual in an oil-hardening tool steel that some tool 
I makers do not even know that such a thing is possible. 
They should try Stentor. 

MACHINABILITY: Again, because of the absence of 
complicated, hard-machining alloys, Stentor is the easiest 
I of all oil-hardening tool steels to machine. It cuts just 
about the same as water-hardening tool steel. 

' USES OF STENTOR: The rule of the Matched Dia- 
gram is — use Srenror in place of No. 11 Special (WATER- 

IHARD) whenever -you want greater accuracy or safety 
in hardening. 

Since Stentor is the oil-hardening running mate of 
No. 11 Special, it is likely to be used for the same type of 
| tools. Stentor is most commonly used for:

yfaltimore 
rnon 8260 



Blanking dies 
Forming dies 
Lamination dies 
Molding dies

Thread roller dies 
Trimming dies 
Precision tools 



Broaches 
Cutter plates 
Gauges 
Master tools 
Spindles 
Master taps 
Thread gauges 
Push broaches 



WHEN TO SWITCH FROM STENTOR: 

| If the tool does not require accurate hardening — if it is 
not likely to crack when hardened in water — use No. 11 
| Special (WATER-HARD). 

If you want greater wear resistance — or for working 
I abrasive materials, and if you have some toughness to 
spare, use Hampden (OIL- WEAR). 

If Srenror is not tough enough to resist chipping or 
cracking, do not draw higher than 400° F., change to 
I R. D. S. (OIL-TOUGH). 

THE HEAT TREATMENT OF STENTOR 

To Forge: Forge from a temperature not over 1950° F. 
and allow the forgings to cool in air in a dry place. 

To Normalize: Forgings are normalized by heating to 
1500° F. and cooling in air.

STENTOR 

(OIL-HARD) 

To Anneal: Pack in a suitable container with clean cast 
iron borings, heat uniformly to 1375°/1400° F., and cool 
slowly in the furnace. Average Brinell hardness 170 to 200 

NOTE: If a large amount of metal is removed in ma- 
chining, the resulting machining strains may 
cause warping in hardening. To avoid this, 
first rough machine — then anneal below the 
critical or about 1250° to 1300° F., and cool 
slowly. Then finish machine. Annealing is 
much cheaper than stoning. 

To Harden: Heat slowly and uniformly in a slightly 
oxidizing furnace atmosphere to 1400° to 1440° F., soak 
until uniformly heated throughout, then quench in oil. 
Very small pieces are hardened at 1400° F., pieces about 
If round at 1420° F„ and large pieces at 1440° F. The 
more accurately you observe these temperatures, the more 
accurately your tools will hold size. 

To Draw: The effect of different drawing temperatures 
upon the torsional impact toughness and hardness of 
Stentor is shown below.

The best combination of hardness and toughness in 
*Stentor tools is secured by drawing at 375° to 400° F. It 
is seldom advisable to draw Stentor higher than this. If 
[this is not tough enough, switch to R. D. S. (OIL- 
TOUGH). 

Large sized tools should be drawn longer than one hour. 
Every time you double the drawing time, cut 25° off the 
I temperature— for example :

R. D. S. - 



Type Analysis: Carbon. . 75% 

Manganese 30% 

Silicon 25% 

Chromium. 1.00% 

Nickel 1.75% 

PROPERTIES I 

DESCRIPTION: A tool steel containing a large per- 
centage of nickel is so unusual that R. D. S. might well bl 
expected to have unusual properties. And so it does. 
R. D. S. possesses approximately the same toughness a. 
Solar (WATER-TOUGH) combined with non-deforminl 
properties like Stentor (OIL-HARD). In the short time 
that R. D. S. has been available as a member of the Oif 
Hardening Matched Set, it has licked so many difficult 
tooling jobs that tool makers are now wondering why nj 
one ever thought of a tough non-deforming tool steel 
before. 

DEFORMATION IN HARDENING: The accoml 
panying chart shows typical length changes for R. D. S. 
when quenched from 1475° F. and also when quenche* 
from 1550° F. (See Hardening instructions.) At 1475° F

R. D. S. 

(OIL-TOUGH) 

DECARBURIZATION: R. D. S. has no special ten- 
Idency to decarburize. If the hardening instructions are 
carefully followed, the tools should be hard right out to the 
| surface. 

MACHIN ABILITY: R. D. S. machines a little tough 
llike Solar. It would be rated as intermediate between a 
plain carbon, water-hardening tool steel and High Speed 
.Steel. 

USES: R. D. S. is used in three ways — 

1. As the tough member of the Oil-Hardening Matched 
Set, it is used to replace Stentor (OIL-HARD) for 
all tools that require more toughness than Stentor 
possesses. - Thus you will find it used for special 
taps, punches, blanking or forming dies, trimmer 
dies, thread roller dies, forming rolls, embossing 
dies, etc. 

2. As the oil- hardening running mate of Solar 
(WATER-TOUGH) R. D. S. is used for all tools 
that would ordinarily be made of Solar. Where 
hardening accuracy or cracking hazards make an 
oil-hardening steel necessary, such as intricate 
shear blades, punches, stamps, swaging dies, slitting 
shears, etc. — use R. D. S. Furthermore, since R. 
D. S. is not as subject to surface decarburization 
as Solar, this alone would be a reason for using it 
sometimes in place of Solar. 

| 3. For parts that are not tools at all. There are cer- 
tain machine parts requiring great strength and 
toughness combined with hardness and wear resist- 
ance such as clutch parts, flipper pins, heavy duty 
lathe centers, pawls, dogs, stops, knuckle pins, 

| spindles, fingers, indexing pins, clutch pins, etc. 

Since R. D. S. is "harder than tempered gear steel 

- and tougher than tool steel," it is ideal for parts of 

■ this nature. 

WHEN TO SWITCH FROM R. D. S.: 

I If size change is not important — if no cracking hazard is 
involved in hardening, there is no need to use R. D. S. — 
|use Solar (WATER-TOUGH). 

If greater hardness and wear resistance are needed — and 
|you have toughness to spare— use Stentor. 

■ If the tools get hot in service, switch to a Red-Hard 
Steel— £xce/o or D. Y. O. 

y THE HEAT TREATMENT OF R. D. S. 

To Forge: Forge from a temperature not over 2000° F. 
| and allow the forgings to cool in air in a dry place. 

To Normalize: Forgings are normalized by heating to 
1 1675° F. and cooling in air. 

To Anneal : For parts that have been previously hard- 
. ened or annealed — pack in a suitable container with clean

(OIL-WEAR) 





Type Analysis: Carbon 2.10% 

Manganese 25% 

Silicon 25% 

Chromium 12.50% 

Nickel 50% 

PROPERTIES 

DESCRIPTION: Hampden is an oil-hardening, high ' 
carbon, high chromium die steel having extreme wear 
resistance. It hardens with very little change in size or I 
shape, Hampden is a deep hard- 
ening steel like High Speed tool 
steel and has a very high compres- 
sive strength. 

Because of its high percentage of 
chromium, Hampden has mild 
corrosion resisting properties when 
hardened. 

DEFORMATION IN HARD- 
ENING: Hampden is essentially R<*- Hampden 

ac • . i <- 1 tl °- T * 1775 ° F - 

a non-deforming tool steel. Its 

average behavior is illustrated by 

the chart. For example, a piece 1" long would expand 

about .0008 " in hardening, but when drawn at 400° F., it | 

returns within .0002" of its original length. If drawn 

at 800° F., it will be a shade under size and above this it 

expands again.

HAMPDEN 



(OIL-WEAR) 

If Hampden is overheated in hardening, it will shrink 
very badly — hence it must never be hardened above 
1825° F. 

DECARBURIZATION: If hardened in an open 
furnace Hampden may acquire a slight soft skin. This is 
not due to any sensitive elements in the analysis — but 
results from the high hardening temperature itself. Pack 
hardening is recommended to avoid this. 

MACHINABILITY: Due to the very high carbon and 
chromium, Hampden cannot be annealed softer than 
about 217 to 241 Brinell. At this hardness, it machines 
about like annealed high speed steel. 

USES OF HAMPDEN: Hampden is used for tools re- 
quiring a combination of hardening accuracy and safety 
with maximum wear resistance and greatest possible pro- 
duction. On the Matched Diagram, Hampden may be 
approached from two directions. 

1. Use Hampden to replace Stentor (OIL-HARD) 
for any tools requiring exceptionally long life or for 
working on abrasive materials — such as 



Edging rolls 
Sub-press dies 
Forming dies 
Fender dies 
Thread rolling dies 
Lamination dies 



Broaches 
Slitting cutters 
Special taps 
Master tools 
Beading rolls 
Forming rolls 

2, Hampden is the oil-hardening running mate of 
K-W (WATER- WEAR). Use Hampden to re- 
place K-W for all tools that must hold size and shape 
accurately — or where the shape makes water 
quenching dangerous, such as: 
Thread gauges Drawing dies 
Spinning tools Extrusion dies 
Long mandrels Reamers 
Long punches Sizing plugs 

WHEN TO SWITCH FROM HAMPDEN: 

If you want greater toughness, at the sacrifice of wear 
resistance, switch to Stentor (OIL-HARD). A second 
step would be to go to R. D. S. (OIL-TOUGH). 

If the tool does not require accuracy in hardening, and 
is safe to quench in water, use K-W (WATER- WEAR). 
K-W will usually show even greater wear resistance and 
longer life than Hampden. 

If you prefer an air-hardening high carbon, high chro- 
mium steel to one which hardens in oil, use No. 610 Air 
Hardening Steel. This is not on the Matched Diagram 
but it can be used almost interchangeably with Hampden

for all purposes for which Hampden is recommended. 
(See Page 197 for description of No. 610 Steel.) 

THE HEAT TREATMENT OF HAMPDEN 

To Forge: Hampden forges very much like high speed | 
steel. Heat slowly and uniformly to a temperature be- 
tween 1950° and 2050-° F. and forge. Do not continue | 
forging below 1700° F. but reheat as often as necessary. 
Small, simple forgings can be cooled slowly in lime, but 
the best practice for large forgings is to place them in a I 
furnace heated to about 1550° F., soak uniformly at this 
heat, then shut off the heat and cool the job slowly in the I 
furnace. This is not an anneal. To anneal, proceed as 
below. 

Normalizing: Normalizing is not recommended and is 
not necessary after furnace cooling as described above. 

To Anneal: Pack in a suitable container with clean cast 
iron borings, heat uniformly to 1500° to 1530° F., and cool I 
very slowly in the furnace. Brinell hardness 217 to 241. 

To Harden: The following table shows the effect of 
different hardening temperatures on Hampden: ■ 



Oil quenched from

C-61/63

61/63 
54/56 



Note that maximum hardness is secured only between 
1750° and 1800° F. Also Hampden holds size best within 
this range. If overheated Hampden becomes softer- 
it shrinks — and it becomes somewhat non-magnetic. 
Moral — Don't overheat it. 

The best procedure is to pack the tools in clean cast iron 
borings (or charcoal), heat uniformly to 1750° to 1800° F., 
soak thoroughly, then remove the tools from the pack and 
quench in oil.

upon the torsional impact toughness and hardness of v*l 
Hampden is shown on the following page.

It will be observed that Hampden shows two toughness 
peaks— one at 400° F. and the other at 800° F. 

To secure maximum hardness and wear resistance with 
| fair toughness, draw at 400° F. To get greater toughness at 

some sacrifice of hardness, jump directly up to 800° F. 

There appears to be little gained by drawing Hampden 
I anywhere between 425° and 775° F.

HORACE T. POTTS CO. 



1 No. 610 AIR-HARDENING STEEL 

Although it does not appear on the Matched Diagram, 
9his steel is mentioned here because it is so frequently 
used by certain tool makers who prefer an air-hardening 
jj»igh-carbon, high-chromium tool steel. 

The type analysis of No. 610 Steel is: 

-j Carbon 1.50% 

** Manganese 30% 

Silicon 30% 

Chromium 12.00% 

Molybdenum 80% 

m Vanadium 20% 

No. 610 does not become quite as hard as Hampden but 

H: is correspondingly tougher. A tool maker can, if he 

aesires, substitute No, 610 for Hampden on his Matched 

J)iagram and use it for the same purposes as he would use 

mhampden. 

3 THE HEAT TREATMENT OF No. 610 

To Forge: Same as Hampden. See Page 194. 

I To Anneal: Same as Hampden. See Page 194. 
To Harden: Pack harden from 1825° to 1875° F., re- 
move the tool from the pack and cool in air. A blast is 

not necessary. 

■ To Draw: The torsion impact curve for No. 610 is quite 

similar to Hampden. It shows two toughness peaks — 
Jie lower one occurs at 450° F. and the higher one at 
■fco F. The hardness values are shown in the following 

table.

STAR-ZENITH 

HIGH-SPEED STEEL 
(RED-WEAR) 




Type Analysis: Carbon 70% 

Manganese 25% b. 

Silicon 20% ■* 

Chromium 3.75% ^^ 

Tungsten 18.50% ft 

Vanadium 1.10% 

PROPERTIES * 

DESCRIPTION: Star-Zenith is nominally an 18-4-1^ 
type of High Speed Steel. That is— 18% tungsten, 4?JB 
chromium, 1 % vanadium. However, we do not shoot for 
18% tungsten — and get some 17.50's and 17.25's. Star^ 
Zenith is always over 18% tungsten. So, too, with 
vanadium — 1% is our minimum. »_- 

The normal carbon range for 18-4-1 is .65% to .75%. 
Not so with Star-Zenith. You will get no 65 's or 66's ir^ 
this grade. Our carbons are a minimum of .68% — ano™ 
practically all heats are within a point or two of .72% 
carbon. 

This close control of chemical limits permits a constant 
duplication of heat treating results that would not other ( 
wise be possible. 

DEFORMATION IN HARDENING: Srar-Zenir/ft 
holds size very accurately in hardening. For example, a 
1" cube will lose about .0005" in hardening from 2300 ag 
to 2400° F., and will lose a like amount upon being drawn 
to 1050° to 1100° F. The hardened and drawn piece will 
run about .001" smaller than the annealed block. CuttertW 
and form tools will open up slightly in the hole and 
shrink slightly on the O. D. 

DECARBURIZATION: Star-Zenith is particularly 
free from the tendency to decarburize in hardening. SofJ| 
skin is unknown to hardeners who use ordinary care in 
handling this steel. p= 

MACHINABILITY: The machinability of high speed 
steel is too well known to require comment. Star-Zenitt*^ 
is very carefully and thoroughly annealed to produce the^ 
best machinability possible in this type of steel. 

USES OF STAR-ZENITH: It is Star-Zenith's job to™ 

deliver maximum hardness and wear resistance for tools

STAR-ZENITH 

HIGH-SPEED STEEL 
(RED-WEAR) 






that get hotter than about 300° F. in service. Although it 

^|| is frequently used with success for tools that never become 

heated at all, this is not its proper field and there is usually 

=m some other steel of the Matched Set that will do such jobs 

™ better or more economically. 

Star-Zenith is the red-hard running mate of K-W 

q| (WATER-WEAR). There is no more wear resisting steel 

in existence than K-W, but it will lose its hardness and 

[■efficiency if heated above about 300° F. in service. The 

rule of the Matched Diagram is to go east for red-hardness 

-—and here you find Star-Zenith. 

Star -Zenith is the only steel on the Matched Diagram 
suitable for making metal cutting tools that become hot in 
9| service. It is recommended for: 

Lathe tools Reamers Thread chasers 

Planer tools , Broaches End mills 

Drills Milling cutters Gear cutters 

Taps Form cutters Wood knives 

As the most wear resisting member of the Red -Hard 
Matched Set, Star-Zenith plays a small part in other 
| types of hot working tools. When drawn at tempera- 
tures between 1200° and 1400° P., it has some ductility and 
JM is useful for certain hot working tools that have flat or 
convex working surfaces, such as hot shear blades, hot 
_ punches, grading roll inserts, flat coining dies, etc. Tools 
I of this nature made of Star-Zenith should not be water- 
cooled during service. 

HwHEN TO SWITCH FROM STAR-ZENITH: 

If the tool does not become heated in service — and red- 
| hardness is not necessary — K-W or Hampden will usually 

do the job more efficiently or more economically. 
i If greater toughness is needed than can be secured in 
Star-Zenith by drawing it down to C-45 Rockwell, 
switch to D. Y. O. (Red-Hard). 

* THE HEAT TREATMENT OF STAR-ZENITH 

^ To Forge: Heat slowly and uniformly to 190072050° 
B F. and forge. Do not work the steel below 1600° F. but re- 
heat as often as necessary. Small, simple forgings can be 
| cooled slowly in lime, but the best practice for large 
forgings is to place them in a furnace heated to about 
■I 1550°/1600° F„ soak uniformly at this heat, then shut off 
™ the heat and cool the job slowly in the furnace. This is 
not an anneal, and when cold the forging must be annealed 
■ as below. 

Normalizing: Normalizing is not recommended. 
% To Anneal: Pack in a suitable container with clean cast 
iron borings, heat uniformly to 1550° to 1600° F., and cool 
m very slowly in the furnace. Brinell hardness 217 to 241.

To Harden: Preheat slowly and uniformly to 1500° to 
1600° F. and soak a reasonable time to heat the section 
throughout. Transfer to a super heating furnace with a I 
reducing atmosphere at 2300° to 2400° F.— avoid soaking 
at the superheating temperature — and quench in oiL || 
Small sizes or delicate sections, or large hot-work dies may 
be hardened by cooling in still air. — ^ 

The average hardness values to be secured at various •■ 
hardening temperatures are given in the table below. 

Be sure to quench Star-Zenith tools below 200° F. | 
before drawing them. 

To Draw: It will be observed that Torsion Impact I 
curves are not included for the three Red-Hard Steels. 
These steels are intended for use at elevated temperatures, — h= 
and thus far, our toughness tests have all been made on ^"" 
specimens at room temperature. We cannot be sure that 
such toughness data would be applicable at elevated | 
temperatures. 

We have much Torsion Impact data on Star-Zenith Mb 
which would be helpful to a hardener who wished to ex- 

periment with his heat treatment— and this will gladly be 

furnished upon request. 

Most metal cutting tools made of Star-Zenith High

ft 900° F, This will yield about C-64 Rockwell hardness 
mith a greater measured toughness than a one hour draw at 
1050° to 1100° F, 

■ Hot forming tools made of Star-Zenith should be 
Irawn softer than C-55 Rockwell so that they will have a 

slight degree of ductility. The tools may even be drawn 
Mown to C-45 Rockwell for this purpose — but no softer. If 
^his is not tough enough, switch to D. Y. O. (RED-HARD), 

which hardens to about C-45 Rockwell and will be much 

Kougher than the Star-Zenith at this hardness. Such 
iot forming tools, when made of Star-Zenith, are usually 
air-hardened, and from a lower temperature than cutting 
*ools— namely 2100° to 2300° F.

STAR-ZENITH 

HIGH-SPEED STEEL 
(RED-WEAR) 

HARDENED BITS 

Star-Zenith high speed steel is furnished in the form of standard 
tool- holder bits with 30 degree angle ends. Each piece is hardened 
^eady to be ground and put to work. The cutting edge should be 
;round at least 1/64* below the surface of the bit. 

These are not "trick" bits; they are not made to cut at abnormally 
ast speeds or high temperature. They combine good red-hardness, 
lood toughness and the ability to hold a keen edge for finishing! 
They are ideal tool bits for general shop use— cutting all kinds of 
-ietal — on all kinds of operations— either roughing or finishing. 
Star -Zenith tool bits are furnished from stock in 5 -pound boxes 
ne size or assorted sizes in a box.

. GOLD STAR 

HARDENED BITS 

■ GOLD STAR is a super high speed cutting steel designed for 
Machining at temperatures beyond the capacity of the standard 

brands of high speed steel. Whether the excessive temperature on 
^he cutting edge of the tool results from high speeds, heavy feeds, or 
Bard material, if your present tools are "burning up"— try GOLD 

STAR. This steel is available in annealed flat and square bars— 

also treated tool holder bits in standard sizes.

Tungsten 14.50% 

Vanadium 50% ■ 

PROPERTIES 

DESCRIPTION: D. Y. O. is an all-around hot work-| 
ing die steel for use in the forge shop. Its analysis shows it 
to be a low carbon high speed steel. The high alloy contents 
gives it red-hardness and wear resistance at elevated tem- 
peratures. The low carbon serves to balance this with 
sufficient toughness to make a good general purpose hotB 
working die steel. 

DEFORMATION IN HARDENING: D, Y. O. be-| 
haves very much like high speed steel in this respect. It 
holds size and shape very accurately within the limits that* 
are expected in hot working tools such as it is used for. * 

DECARBURIZATION: D. Y. O. is not subject to sur- 
face decarburization in hardening providing even ordi-™ 
nary care is given to its heating. 

MACHINABILITY: D. Y. O. machines very much! 
like high speed steel — if anything, it is a little softer. 

USES OF D. Y. O.: The principal" field for the steel isg 
in hot compression tools. It does not become hard 
enough for metal cutting tools™ and it lacks the extreme* 
toughness needed in tools subjected to a sharp hammer™ 
blow. It is recommended for bolt and rivet dies, hot 
piercing punches, hot extrusion dies,- bulldozer tools, J 
forging mandrels, semi-hot work dies, etc 

WHEN TO SWITCH FROM D. Y. O.: I 

If the tools do not become heated over 300° F. in service, 
some steel from the Water- Hardening or Oil-HardeningB 
Matched Sets will probably serve better. 

If greater red-hardness and wear resistance is needed! 
switch to Star-Zenith (RED-WEAR). Star-Zenith can 
be drawn back to C-45 Rockwell in order to meet theM 
hardness of D. Y. O. 

If greater toughness is needed than can be secured by« 
drawing D. Y. O. to 1300° F., switch to Excelo (RED™ 
TOUGH).

D. Y. 0. 

(RED-HARD) 

If it is a short run job, Excelo will probably do it at 
'lower cost. 

THE HEAT TREATMENT OF D. Y. 0. 

To Forge : Heat slowly and uniformly to a temperature 
not over 2100° F. and forge. Do not work the steel below 
1 1600° F., but reheat as often as necessary. When fin- 
ished, the forging should be thoroughly reheated to about 
1550° 1600° F. and then cooled slowly — the slower the 
'better. This is not an anneal, and when the forging is 
cold, it must be annealed as below. 

Normalizing: Normalizing is not recommended. 
To. Anneal; Pack in a suitable container with clean 
least iron borings; heat uniformly to 1550° F. ( and cool 
slowly in the furnace. Brinell hardness 197 to 223. 

To Harden: D. Y. O. is hardened by the same practice 
that would be used for high speed steel. 

The tools should be preheated slowly and uniformly to 
15 00°/ 1600° F., and thoroughly soaked at this temperature 
until they are well heated throughout. Sometimes two 
j preheating operations are used — first in a furnace main- 
tained at about 1100° F., then transferred to a second pre- 
heating furnace at 1600° F. 

After preheating, transfer the tools to a super-heating 
furnace at 2250° to 2300° F. When heated uniformly to 
this temperature, quench in oil. Air hardening can be used 
in some cases where the resulting scale is not too objec- 
tionable. 

To Draw: The following table shows the average Brinell 
and Rockwell Hardnesses to be expected with various 
drawing temperatures:

D. Y- 0. 

(RED-HARD) 

At this point the steel is just as hard as it was when 
quenched. 

There is, therefore, no occasion for drawing D. Y. O. 
Steel at a lower temperature than 1100° F. Higher tem- 
peratures than this should be used when greater toughness' 
is desired. 

The tools can be left harder for any given service if the 
forger will take time to warm his tools thoroughly before 
putting them to work. Cold dies are likely to break on the I 
first piece forged and it is a pity to require the hardener 
to draw the tools back tough enough to withstand these! 
first few blows and thus sacrifice hardness and wear re- 
sistance that will be urgently needed when the dies have, 
warmed up. 1

_ PROPERTIES 

■ 

DESCRIPTION: The analysis of Excelo is arranged to 
— give maximum toughness for hot working tools. As much 
: ™ red-hard alloy is* added as is possible without decreasing 
the great toughness which characterizes this steel. 

•• Excelo is a deep hardening steel. It becomes much 
harder than D. Y. O. in the quenched condition but it 
| loses its hardness faster when used at elevated tem- 
peratures. 
*m DEFORMATION IN HARDENING: Being an oil- 
hardening steel, Excelo holds shape and size well in hard- 
— ^ ening. No difficulty need be anticipated from this direc- 
^* tion in hot working tools such as are made from this steel. 
DECARBURIZATION: Excelo is not particularly sus- 
*S ceptible to decarburization in hardening. It is more 
sensitive than carbon tool steel— because of its higher 
■^B hardening heat— but with reasonable care in heating, it 

will harden satisfactorily on the surface. 
^m MACHINABILITY: This steel machines intermediate 
^^ between water-hardening tool steel and high speed steel. 
It is the easiest of the Ffed-Hard Matched Set to machine. 
• USES OF EXCELO: Excelo is used for hot working 
tools requiring the greatest possible toughness — particu- 
I larly tools subjected to heavy hammer blows or tools con- 
taining deep recesses or sharp corners. For short-run 
jmmM jobs, Excelo can be used with economy for the same tools 
"^^ as recommended for D. Y. O, (RED-HARD). It has proved 
very successful for square bolt dies, bulldozer dies, Maxi- 
S pres dies and hot shear blades having notched edges. 

EJgWHEN TO SWITCH FROM EXCELO: 

If the tools do not become hot in service, the use of a red- 
l^hard steel is not advised. Solar (WATER-TOUGH) or 
** /?. D. S. (OIL-TOUGH) will usually do a better job 

and cost less.

EXCELO 



(RED-TOUGH) 

If more red-hardness and wear resistance at elevated 
temperatures is needed, use D. Y. O. This change becomes 
increasingly necessary as the tool temperature increases. 

THE HEAT TREATMENT OF EXCELO 

To Forge: Forge from a temperature not over 2050° F. 
Cool the forgings in air in a dry place. 

To Normalize: Forgings are normalized by heating to 
1 700° F. and cooling in air. 

To Anneal : Pack in a suitable container with clean cast 
iron borings, heat uniformly to 1440° to 1475° F. and cool 
slowly in the furnace. Brinell hardness 197 to 223. 

To Harden: Slow preheating is not as essential on 
Excelo as it is on the higher tungsten tools which do not 
have so much toughness. It is, however, good practice to 
preheat the tools on the fore-hearth of the furnace until 
they have acquired a dull red color, then heat to 1700° F., 
soak for sufficient time to heat thoroughly and quench in oil. 

To Draw: Excelo tools should be drawn at least as hot 
as they will become in service— generally somewhat hotter. 

The following table gives average hardness values to be 
expected at various drawing temperatures:

There is slight evidence of secondary hardness at a draw- 
ing temperature of 1000° F. Experience shows that Excelo 
should seldom be drawn lower than this temperature. 

It is easy to become confused by the high hardness values 
of Excelo compared to D. Y. O. This is due to the fact 
that these hardness values are taken at room temperature 
and that is not where the dies do their work. D. Y. O. 
Steel is only slightly softened by high operating tempera- 
ture while Excelo is considerably softened. Therefore,

hen the tools are actually at work at say 1000° F., 
D . Y. O. is harder than Excelo. Also, the wear resistance 

<B>f D. F. O. is considerably greater due to its high alloy 
content. 

M Starting at a minimum drawing temperature of 1000° F., 
greater toughness in Excelo can be secured by raising the 

^rawing temperature if experience indicates that this is 

a ^iecessary.

STAINLESS 

AND HEAT RESISTING 

STEELS 

Even though Stainless Steels have been in use 
for several years, there is still considerable con- 
fusion existing as to the properties and correct 
applications of the many analyses of corrosion 
resisting steels. 

"Stainless Steer' is a general term, embracing 
many analyses, each one developed for some par- 
ticular purpose. It is obvious that with so many 
different types, a wrong application— that is, the 
use of a wrong type— will jeopardize the useful- 
ness of the steel. We are in a position to give ex- 
pert advice on application and fabrication. 

Horace T. Potts Co. have been pioneers in the 
development and sale of special steels and can 
supply Stainless Steel in all available forms in the 
correct analysis for the purpose intended. The 
mills for whom we are distributors are among the 
leading producers of the various forms of Stain- 
less and Heat Resisting Steels, such as: 

SHEETS AND LIGHT PLATES 

STRIP 

PLATES 

TUBES and PIPE— Seamless, Welded and 
Clad 

FITTINGS— Screwed, Flanged and Com- 
pression. 

BARS— Hot Rolled, Cold Finished and 
Ground — Annealed or Treated

STAINLESS AND 

HEAT RESISTING 

STEELS 

18-8 Type 302 

Type Analysis: Carbon .10%; Chromium 16-20%; 
Nickel 8-12%. 

18-8 is unsurpassed in resistance to corrosion and will re- 
main permanently bright and untarnished under many 
conditions. It is not affected by moisture, salt water, milk, 
fruit-juice, or foodstuffs. A large variety of chemical 
solutions and liquids used in the industrial field has no 
effect upon 18-8. It has excellent resistance to high tem- 
peratures, scaling comparatively little below 1600°-1650° F, 

18-8 offers the maximum ease in stamping, forming, 
and welding operations, and may be readily soldered. 

18-8 S Type 304 

This type differs from 18-8 Type 302 only because of its 
low carbon content. The carbon in this grade may be 
specified as low as .07% max. Where considerable welding 
is to be done and where the corrosive conditions are not 
severe, Type 304 makes possible a higher corrosion re- 
sistance at the weld and adjacent material due to less 
carbide precipitation in and around the weld area. 

18-8 FM Type 303 

This alloy has all the desirable characteristics of the 
regular 18-8 Stainless Steel, but it does not have its 
difficult machinability. The 18-8 FM (Free-Machining 
Alloy) is so freely machinable that it can be readily handled 
on automatic screw machines at 60 to 70% of the speed of 
ordinary screw stock. The improvement of machinability 
is obtained without loss of corrosion resistance or physical 
properties. 

18-8 FM Stainless — Free-Machining Type is available 
promptly in a wide variety of sizes and shapes, and in all 
finishes, Hot Rolled, Cold Drawn, Ground and Ground 
and Polished. 

18-8 S MO Type 316 

Type Analysis: Carbon .10% max.; Chromium 16 to 19%; 
Ni. 14% max.; Molybdenum 2 to 4%?. 
A superior corrosion resistant to many of the heavy 
chemicals. Used extensively for Dye Vats and Sulphuric 
Acid Equipment. Having excellent Resistance to Inter- 
Granular Corrosion, is used for many fabricating jobs 
requiring welding. 

18-8 Ti Type 321 

A stabilized 18-8 Stainless Steel containing Titanium. 
This type makes heat treatment after welding unnecessary 
and eliminates carbide precipitation adjacent to the weld 
areas. 

25-12 Type 309 

Type Analysis: Carbon .28% max.; Chromium 22-28%; 
Nickel 12-16%. 
25-12, while highly resistant to a wide variety of 
corrosion agents, is intended primarily for use at high 
temperatures. It does not oxidize rapidly below 2100° F., 
and in addition, retains a large proportion of its strength 
and toughness throughout its range of application. 
25-12 is an outstanding development in heat resistant 
alloys and will stand more forming and manipulation than 
the straight chromium alloys. 

216 



HORACE T. POTTS CO. 



1 17 Type 430 

Type Analysis: Carbon .10%; Chromium 16-18%. 

This is the leading member of the straight chromium 
alloy series for general purposes, and is widely used in 

— many arts and industries. It resists atmospheric corrosion 
I indefinitely, also many chemicals, and withstands tem- 
peratures as high as 1500° F. without scaling. 

— 17 is suggested for conditions when the extreme duc- 
Btility and great ease in fabrication of 18-8 is not necessary. 

■ 12 Type 410 

— Type Analysis: Carbon .10%; Chromium 12-14%. 

This is a straight chromium alloy which may be heat 
treated to high physical properties. Heat treatment also 

■ improves corrosion resistance. It finds many applications 
^in machine parts, such as shafts, pump rods, bolts, etc.

12-Z Type 416 

This alloy offers all the characteristics obtainable with 
'the regular 12/14 straight Chrome type of Stainless Alloy, 
and in addition is a free-machining steel that will machine 
lin automatics at approximately the same speed, and with 
■the same tooling, as ordinary screw stock. It also grinds 
rapidly, saves abrasives and has special non- galling and 
I non-seizing properties. This alloy may be heat treated to a 
■hardness of about 331 Brinell. 

12-Z Stainless — Free-Machining Type is available 

» promptly in a wide variety of sizes and shapes, and in all 
finishes, Hot Rolled, Cold Drawn, Ground and Ground 
and Polished. 



27 Type 446 

I Type Analysis: Carbon .10%; Chromium 25-30%. 

A high chromium steel, used principally for service 
| at temperatures between 1500° and 2100° F. It is used 
for furnace parts, air and gas pre-heating, annealing 
boxes, exhaust manifold valve, etc.

The Stainless and Heat Resisting grades and Type 
numbers briefly described on these pages are the most 

| popular analyses and they cover the largest field of appli- 
cations. There are, however, many other grades and we 
will welcome the opportunity to send you complete data 

I on all types as well as more detailed information on the 
steels shown.

LABORATORY CORROSION ■ 
DATA | 

Showing resistance of USS Stainless Steels 
to various chemicals and acids ' 

The following data are results of laboratory tests con- ■ 
ducted by Fried Krupp, A. G. In using this data it should 
be understood that results of laboratory tests are indic- 
ative only of the conditions under which they are run, | 
and may be considered as a basis for recommendation, 
but not for guarantee. As actual operating conditions I 
can rarely be duplicated in the laboratory it is desirable 
to further test under actual service. The letters A, B, . 
C, etc., represent the approximate corrosion expressed 1 
in inches penetration per month as follows:

I FABRICATION DATA FOR 
I USS 18-8 STAINLESS 

1 



STEEL 

FORGING 

■ USS 18-8 is a strong material; at elevated temperatures 
its strength is so superior to that of iron and low carbon 

3 steel that it forges much more slowly, and less reduction 
will result from the usual blows under the hammer. It 

9 may be forged at temperatures between 2200° and 1800° F., 
but light blows of the hammer should be used at the start. 

■ Heating, which Tequires a longer time than is allowed for 
ordinary steels, should be done slowly until a temperature 

3| of 1500° to 1600° F. is reached; then more rapidly to full 

forging temperature. Soaking at the full forging tempera- 

Jl ture should be avoided. It is advisable to reheat when the 

work cools down to 1800° to 1750° F., rather than to at- 

■ tempt much deformation of the stiff metal below this 
temperature. 

=3 ANNEALING 

_— Since USS 18-8 is not hardenable by heat treatment 
^^and does not undergo transformations upon cooling, the 
^_ term "annealing," as here applied, has a somewhat dif- 
"™ ferent significance from that usually understood. Anneal - 
^_ing USS 18-8 is accomplished by heating to at least 
^* 1850° F. and then cooling rapidly. The treatment produces 
^ m a completely austenitic structure of minimum grain size 
^^ which, for numerous applications, is most desirable. 
^_ Maximum ductility or softening is obtained by heating to 
*™ about 2050° to 2150° F. and cooling rapidly. For heavy 
— sections the rapid cooling should preferably be obtained 
^^by quenching, while in the case of light sections it is suffi- 
cient to air cool. The function of the anneal in the case of 
^^U S S 18-8 is to remove cold work effects, homogenize the 
structure and dissolve any carbide particles which may 
""have separated out within the metal at some intermediate 
temperature. By proper annealing, the metal is restored to 
"^■the condition in which it has the maximum ductility and 
softness. It is advisable to cool from the annealing tem- 
■•perature as rapidly as possible, since no harm results 

from the most drastic quench.

allowed to remain long at temperatures between about

metal be allowed to cool slowly through this range except 
when it will subsequently be reheated to a temperature 
above 1850° F. This requirement eliminates any possi- 
bility of annealing 18-8 in the manner commonly followed 
with the plain carbon steels, which are annealed by heating 
to a relatively low temperature and cooling slowly. In 
the case of severely corrosive conditions, 18-8 that has f«g 
been so treated will have its resistance impaired to a degree 
dependent upon the length of time it was subjected to the ■ 
damaging temperature and the nature of the corroding 
medium. Under such conditions, attack will take place ■ 
intergranularly ; the application of a severely corrosive 
condition such as pickling sometimes resulting in complete MMfa 
disintegration. 

U S S 18-8 is less susceptible to this impairment or de- 
terioration than were the earlier "18 & 8" alloys; never- 
theless, for complete realization of the inherent perma- gpfcfg 
nence of the alloy, the rule against the 1000° to 1600° F. 
temperature range should be observed. 

Exceptions to this statement are explained in the chap- 
ters dealing with the alloys U S S 18-8 S and U S S Stabi- ppg 
lized 18-8, and should be referred to in this connection. 



WELDING ■ 

U S S 18-8 is not air hardening, and consequently . 
yields ductile welds by electric resistance, electric arc, or 
acetylene torch methods, provided certain precautions . 
are observed. It cannot be hammer welded successfully. 
Generally, resistance or arc welding will be found the , 
more convenient, except for very thin sections, on account 
of the greater ease in controlling certain important 
operating conditions. However, a little practice will' 
enable a competent welder to secure excellent results with 
this alloy by either gas or electric methods. A welding rod 
of low carbon U S S 18-8 should be used. 

For gas welding: Be sure the surfaces to be welded 
are clean and free from scale. 

Use only sufficient oxygen to insure a non-carburizing 
atmosphere around the hot metal. Maintain the flame as 
small as possible, and practically neutral. An oxidizing 
flame produces unsound welds, while a carburizing flame 
(one containing an excess of acetylene) produces brittle 
welds having a low order of corrosion resistance. 

Direct the flame toward the unfinished work, thereby 
preheating. 

Weld straight ahead and do not "puddle." 
228 






HORACE T. POTTS CO.

Use an uncoated welding rod of diameter about equal 
to the thickness of the material being welded, except for 
thicknesses over % -inch, for which 34 -inch rods may be 
used. 

For arc welding: Be sure the surfaces to be welded 
are clean and free from scale. 

The electrode is positive; the work negative. Proper 
regulation of the current is readily obtained after a 
familiarity with the welding characteristics of this alloy 
has been gained. About 35 volts (open circuit) with 60 to 
65 amperes is generally satisfactory for a %-inch ro< i; the 
current increasing with the rod diameter. 

Use a coated rod of diameter about equal to the thickness 
of the material being welded. The coating should not con- 
tain carbon in a form which may be absorbed readily 
during the welding operation. 

It is preferable to lay several medium beads, with inter- 
mediate cleaning away of the slag formed, rather than to 
attempt to weld with a single heavy bead. The cleaning is 
best accomplished by light hammering with a blunt tool, 
or with a stiff wire brush. 

For resistance welding: The usual spot and seam 
welding processes may be readily applied to this grade of 
steel. 

Welds of U S S 18-8 have satisfactory physical proper- 
ties, but since during welding the metal is exposed to 
I intermediate temperatures, the welds (and especially the 
metal adjacent thereto) may, in general, not possess 
I maximum corrosion resistance. Hence, wherever feasible, 
the welded article should be annealed as indicated under 
I "Annealing," if it is to withstand the most severe forms of 

corrosive attack. 
. The U S S 18-8 S and U S S Stabilized 18-8 alloys are the 
exceptions here also, as mentioned previously under 
I "Annealing," and the chapters dealing with these alloys 
should be consulted. 

FORMING AND DEEP DRAWING 

I US S 18-8, while a more ductile metal than ordinary 
steel, is at the same time a stronger material, work hardens 

I more rapidly, and accordingly requires more power in 
forming operations. In general, slower speeds are ad- 

I visable, especially in the case of equipment originally de- 
signed for the softer materials. Solid steel dies are pref- 

I erable; the deep hardening, non-deforming types of alloy

tool steels being well adapted as die steels for forming i 
U S S 18-8. Extremely well polished dies are the most 
satisfactory. A clearance about twice that used for ordi- i 
nary steel or brass is usually considered good practice. 
Dies should be designed with the allowance for spring-back i 
two or three times that for ordinary steel. 

Forming and drawing operations on U S S 18-8 demand i 
effective lubricants. From several standpoints, the so- 
called water-soluble drawing compounds are quite satis- i 
factory. Linseed oil mixed with whiting and sulphur, as 
well as lithopone, are effective lubricants in some opera- i 
tions. The lubricant should be removed from the stamped 
articles after forming is completed. i 

Forming operations are best applied to annealed 
U S S 18-8. Severe draws are possible without intermediate . 
annealing, but whenever annealing becomes necessary 
the lubricant must first be removed, hence the necessity of , 
considering this factor in the choice of lubricant. If not 
cleansed the metal will become contaminated (par- , 
ticularly carburized) by the decomposing lubricant, and 
its final properties and surface appearance may be im- , 
paired. 

After annealing, which should consist of heating to 
1850° F. or above, and quenching in water (or air cooling 
in thin sections), the metal should be pickled before con- 
tinuing with the forming operations. This cycle may be 
repeated as often as necessary. 

The adaptation of U S S 18-8 for cold forming operations 
is materially facilitated by a pre- warming ^of the blanks or 
dies, or both, to a very moderate temperature, such as 
300° to 500° F., or any temperature which will not act to 
soften the dies by tempering. Working in this manner is 
accompanied by less hardening during deep drawing opera- 
tions and may suffice to eliminate an annealing operation. 
This procedure is covered by a process patent assigned to 
the United States Steel Corporation. 



RIVETING 

U S S 18-8 lends itself readily to either hot or cold 
riveting. Small rivets, up to about ^-inch, niay be driven 
cold, and are set most advantageously by a comparatively 
few heavy blows. Hot rivets should be heated out of 
contact with flame to a temperature of 2100° F., and be 
set rapidly so that mechanical deformation is finished 
before they cool below 1800° F. 
230 



HORACE T. POTTS CO. 



^ SPINNING 

Owing to the high ductility of U S S 18-8, it is well 
^(adapted to spinning operations. Being a strong metal 
and one which grows stiffer with cold work, it will require 
sj^nore power than is needed for brass. The spinning tool 
should have a fairly large radius, and the operation should 
^gbe conducted at definitely slower speed than is customary 
with softer materials. When the total deformation ex- 
SJceeds that which can be accomplished in one operation, 
the work should be annealed, as outlined previously, and 
Jp>ickled. This involves removing the lubricant, and ac- 
cordingly the water-soluble lubricants are most con- 
JJvenient. The thin sections employed in spinning can be 
heated very quickly and need be held in a muffle furnace 
J^br only about 5 minutes, followed by a quick cooling in 
the air or a water quench.

PICKLING 

' A hot pickling solution is required for USS 18-8. The 
temperature should be approximately 150° F. Either 
hydrochloric (muriatic) acid or its equivalent (sulphuric 
acid and common coarse salt) is used. Sulphuric acid 
©lone may be too slow in action to be practical. 

It is customary to employ a solution made by mixing 
fequal volumes of commercial hydrochloric acid and water. 
Where sulphuric acid and rock salt are used, 10% sul- 
phuric acid and 10% salt, heated to approximately 180° F., 
is satisfactory. 

I Nitro-hydrofluoric acid may also be used; a mixture of 
10% nitric acid and 1 to l l A% hydrofluoric acid, used at 
R25° to 130° F., will be found satisfactory. 

A bright finish is secured by adding a small amount of 
liitric acid to the hydrochloric acid pickling solutions. 
The usual bright pickle solution consists of 4 volumes con- 
centrated hydrochloric acid, 4 volumes water, and J^ to 1 
volume concentrated nitric acid. Heavily scaled articles 
■hould be pickled in a solution consisting of 8 volumes 
concentrated hydrochloric acid, 7 volumes concentrated 
Isulphuric acid, and 15 volumes water, prior to using the 
bright pickle solution, 

I It is advisable to add a suitable inhibitor to the solu- 
tions used for pickling stainless steels. A number of satis- 
factory inhibitors are readily available commercially. 
After all pickling operations the pickling acid should 
rinsed off in hot water and the work than be given a

few minutes in hot 10% to 20% nitric acid (about 125° to | 
140° F.), followed by a wash in hot water. 

The ideal tank for the nitric acid dip solution is one] 
made of U S S 18-8, or one lined with this metal. 



PASSIVATION OF FINISHED ARTICLES | 

During machining, riveting, forming, polishing, etc., 
foreign particles may become embedded in the surface! 
of the stainless steel, and unless there are removed they 
will subsequently lead to rust spots. To avoid this poten-| 
tial source of trouble, the finished article should be swabbed 
or immersed for a few minutes in hot 10% to 20% nitric | 
acid (about 125° to 140° F.), followed by a wash in hot 
water, as mentioned under "Pickling." This treatment | 
insures the restoration of the protective surface film, upon 
which rustlessness depends. 



OPERATIONS INVOLVING CUTTING 

A. Sawing — U S S 18-8 is not cut with the same ease as IE 
ordinary annealed steel, nevertheless it is satisfactorily cu t 
by the saw. A high speed steel saw, rather heavilyiB 
weighted, should be used and so applied that the first 
stroke definitely cuts the metal. If the work heats it wilpP 
cut somewhat better. A wavy set saw is particularly wel l 
chosen for this metal. It is disadvantageous to permit theB 
saw to ride over the work without cutting, as this quickl y 
work hardens the USS 18-8 locally,* and renders th<H 
operation much more difficult. ^^ 

B. Machining — The art of cutting USS 18-8 majj 
be summed up by the recommendations— (1) slow speed, 
(2) heavy cut, (3) sharpest tools, (4) generous rake. If thj| 
work warms up considerably, the cutting is easier. It may 
be machined dry or with lard oil-sulphur lubricant. 

C. Drilling— 'Drilling involves the same considerations 
as machining. Use a very sharp drill — preferably of riigrj 
speed steel. Make the drill cut all the time, but remove 
and cool occasionally. The work should be backed up s<J 
that the drill cuts through without punching out the last 
metal. If a lubricant is required, the lard oil-sulphu|| 
mixture is effective. 

D. Threading — The same general rules apply as foj 
other machining operations. A four- or five-thread lead is 
advisable. 

232 



HORACE T. POTTS CO. 



PUNCHING AND SHEARING 

As a further adjustment to the very great toughness 
and elongation of U S S 18-8, the engaging parts employed 
for shearing and punching must fit more neatly than those 
used for ordinary steel; otherwise, metal may drag be- 
tween the punch and the die. In punch work it is necessary 
to punch all the way through the stock, in order to obtain 
clean edges and clean parting of the metal. Shear blades 
must press together closely. 



kiladelphia 
iGent 7450 
►ark 5351 



SOLDERING 

5=*m Notwithstanding the protective character of the surface 

of U S S 18-8, it may be soldered, provided a sufficiently 
^^1 strong agent be used to develop a clean metal surface. 

The hydrochloric acid-zinc chloride combinations (muri- 
so^latic acid cut with zinc) are effective. Polished surfaces 

are more resistant to etching by the soldering fluid and, 
BS therefore, some little time should be allowed. Care should 

be taken to prevent the contact of flux with metal away 
HBfrom the seam, and any excess should be removed by 

thoroughly scrubbing and washing the finished articles, 
^■3 using a mild alkali solution. 

Because of the ease of welding U S S 18-8, and the 
59 possibility of deleterious effect on the metal, it is, in 

general, inadvisable to braze, although brazing is easily 
ZZ3 accomplished. 



POLISHING 

The methods of polishing U S S 18-8 vary so greatly 
with the nature of the articles that it is impossible here to 
give any detailed instructions. Therefore, only a few 
general suggestions are offered. 

The most suitable abrasives are those of the silicon 
carbide or aluminum oxide type. They should be used on 
a soft grease wheel. Stearic-base grease is preferable to 
the petroleum-base grease on account of its higher soften- 
ing point. In general, dry grinding should never be used 
and, for obvious reasons, iron oxide polishing compounds 
should not be applied to the stainless steels. 
' Grinding speeds should not exceed 8,000 feet per minute, 
although final buffing speeds may reach 10,000 feet per 
'minute without damage. Higher grinding speed roughens 
the surface in a characteristic manner. In general, after 
the last grinding, it is advisable to brush before buffing.

HORACE 1. POTTS CO. 



CARPENTER WELDED 
STAINLESS STEEL 
PIPE AND TUBING 

Carpenter Welded Pipe and Tubing has many advantages. It is 
made from Cold Rolled Strip Steel and is therefore inherently sound 
and homogeneous. Both inside and outside surfaces of the tube 
represent surface metal from the original ingot. The weld is made 
automatically under exact control and is scarcely distinguishable 
from the rest of the tube — either physically or chemically. 

Carpenter Stainless Welded Pipe and Tubing in the dead soft 
condition is sufficiently ductile at room temperatures for practically 
all bending operations. If possible the weld should be kept on the 
inside of the bend, or on neutral axis. This, however, is not abso- 
lutely necessary. Expanding operations can be satisfactorily per- 
formed with less tendency to crack than most stainless tubes. 
Carpenter welded pipe and tubing may also be soldered, welded, 
polished, machined, etc.

fit is important to note that this is the original full 18-8 S MO p 
analysis containing the high Chromium and not the modified — 
analysis with lower Chromium content which the present Type 
No. 316 also covers. The 18-8 S MO grade has many advantages for M 
use in the dye and chemical industries. Because of the increasing ■ 
demand for this grade our mill has in stock 18-8 S MO in the above 
Welded Pipe sizes and in the Welded Tubing sizes shown on the g 
next page, both available for immediate delivery. ■

CARPENTER WELDED 
STAINLESS STEEL 
PIPE AND TUBING 

It is always economical to take full advantage of the higher 
physical properties of Stainless tubing by using the lightest possible 
wall, There are several types of joints available for making pressure- 
tight connections on light gauge tubing. Fittings for these joints 
are being manufactured in Stainless Steel and information can be 
furnished on request. •

The above Bar Stock Valves are in Philadelphia stock in both 18-8 
and 12/14% Cr Stainless Steels, except Angle valves of 18-8 Stainless £ 
are carried only in l A" size. Can obtain 
%" and 1* promptly from factory stock. 

Stainless Steel Bar Stock Valves manu-B 
factured by Reading-Pratt & Cady Com- 
pany, Inc., are precision turned from Free 
Machining grades of Stainless Steel in bothfl| 
the 12/14% Chromium and the 18% Chrom-" 1 
ium 8% Nickel types. These valves are 
low in price. They fill the need for close ■ 
control valves capable of withstanding high 
working temperatures and pressure. 

The pipe threads on all Bar Stock Valves areM 
considerably longer than the effective length 
called for in the American Standards and in 
the American Petroleum Institute Standards. ■ 
Ports are of a larger diameter than ordi- 
narily found in small plug type valves. 
Their area is the same as that of double extra heavy pipe. The ■ 
extra rugged stems of scientifically designed threads are always in 
contact. The pitch is sufficiently fine to give close control.

POTTSCO 19-9 S 
STAINLESS STEEL 
WELDING WIRES 



Available for either Gas or Electric Welding. Gas wires are 

furnished bare. Electrodes are coated for shielded-arc type of electric 

jj^ welding. This coating is designed to improve the welding qualities 

jqM of the electrode and also compensate for changes in analysis which 

^ m would otherwise occur during the welding operation. 

POTTSCO 19-9 S Stainless Steel Gas Wires and Electrodes produce 
jj— weld metal which is ductile and corrosion resistant. Welds can be 
SI machined and will take a high polish. They are resistant to corrosion 

from atmospheric and other moistures, salt water, milk, foodstuffs 

and most organic or inorganic chemicals. 
0^ POTTSCO 19-9 S is used more widely than any other stainless 
_^K steel grade. However, where it is desirable to use exactly the same 
*™ metal type as in the part being welded, POTTSCO Gas Wires and 

Electrodes are available in any standard stainless steel alloy. See 
^_ partial list below all of which are ready for prompt shipment.

THE USE OF PHYSICAL 

PROPERTIES IN SPECIFICATIONS 

FOR STEEL 

Frequently steels are specified by analysis only, without 
proper regard for physical properties. In many cases the 
S.A.E. specifications which cover chemical analyses only 
are used. Physical properties are of greater importance 
and should be an integral part of any specification covering 
steels for machine parts. 

In machine designing the physical properties must be 
considered. It is not sufficient to merely give chemical 
analysis. When shafts or other machine parts fail, it is 
not because the steel did not contain 1% chromium, or 
3 l A% nickel, or .40 carbon, but because these parts have 
insufficient physical properties. Therefore the physical 
properties should be improved. 

In deciding on the physicals to be specified it should be 
borne in mind that Fatigue Resistance, Shear Strength, 
and Torsional Strength are all proportional to Tensile 
Strength. The Yield Point is of value because it is truly the 
working limit of a steel. Elongation and Reduction of 
Area, which are measures of ductility, are valuable because 
they indicate the shock and impact resistance of steel. 

The American Society for Testing Materials has en- 
dorsed specifications that cover both chemical and 
physical properties. We give below four groups that cover 
the range of tensile properties from soft steel to the highest 
quality heat treated alloy steel.

NOTE: There is, as yet, no A.S.T.M. specification 
covering this type of steel. This type, however, cannot be 
left out, for it offers a desirable range of physical properties, 
filling in the gap between carbon steel and heat treated 
alloy steel. This grade of steel offers tensile properties in 
excess of those obtainable with plain carbon steel, or an- 
nealed and untreated alloy steel, at the same time having 
superior machining qualities.

EXPLANATION OF THE S.A.E. 
NUMBERING SYSTEM 



The numerical index system, commonly referred to as the S.A.E. 
Standard System, was developed by the Society of Automotive 
Engineers, Inc., to provide a simple means of indicating the chemical 
composition of the various steel grades in more common use. The 
present revision has been brought about by the development and 
general application of numerous new steel analyses during recent 
years and the necessity for extending the system to cover them. 

The system is based on the use of numbers composed of four or 
five digits, and certain letters used as prefixes. The first digit of the 
standard number indicates the type to which the particular steel 
belongs. Thus "1" indicates a carbon steel, "2" a nickel steel, 
"3" a nickel-chromium steel, "4" a molybdenum steel, etc. In the 
case of the alloy steels, the second digit, and sometimes the third, 
usually indicates the approximate percentage of the principal alloy — 
in the case of simple alloys, the alloy from which the steel is named. 
The final two (sometimes three) digits indicate the mean carbon 
content in "points," or one-hundredths of one percent. Thus, "2320" 
indicates a nickel steel of approximately 3% nickel content (3.25%/ 
3.75%) and .20% average carbon (.15%/.25%); "52100" indicates 
a chromium steel of more than 1% average chromium content 
(1.20%/1.50%, as compared with .60%/.90% or .80%/1.10% 
for the 5100 series) and 1.00% carbon (.95%/1.10%), while "71360" 
indicates a tungsten steel of 13% tungsten content (12%/15%) 
and .60% carbon (,50%/.70%). 

The prefix "X" is used in several instances to indicate variations 
in the range of sulphur, manganese and chromium, and the prefix 
"T" is used with Manganese Steels to indicate a higher range of 
manganese than that found in steels of the XI 300 series. 

Basic numerals of the system are;

Sheet mills roll iron and steel sheets to U. S. Standard 
Gauge unless otherwise ordered. Plate mills usually roll 
heavy plates J{ 6 " and heavier, and light plates No. 8 to 
No. 12 to Birmingham Gauge. 

The low temperature (as compared with iron) at which 
steel plates have to be finished, causes a slight springing 
of the rolls, leaving the plate thicker in the center than on 
the edge. This is especially noticeable in plates less than 
Y% ' thick and over 66 " wide, which may be of full thickness 
on the edge and yet be as much as Y% " thicker in the middle.

APPROXIMATE WEIGHTS OF 
VARIOUS METALS 

To find the weight of various metals, multiply the con- 
tents in cubic inches by the number shown below; the result 
will be the approximate weight in pounds. 

Iron 27777 Brass 3112 Tin 26562 

Steel 28333 Lead 41015 Aluminum .09375 

Copper.. .32118 Zinc 25318 

Steel Bars — Flats and Squares. To find the approxi- 
mate weight per lineal foot of bar, multiply width times 
thickness times 10 and divide by 3. Example; (J^ in. x 
6 in. flat): )^x6x 10 divided by 3 gives 10 lbs. per foot. 
(Actual is 10.2 lbs.) 

Rounds. To find the approximate weight per lineal 
foot of bar, multiply the diameter times the diameter 
times 8 and divide by 3. Example: (2 in. round): 2x2x8 
divided by 3 gives 10.67 lbs. per ft. (Actual is 10.68 lbs.)
